Cursive fonts simply emulate cursive handwriting, in which letters are usually connected together in a slanted and flowing manner. However, for different languages, cursive writing can mean differently, for example, for. This generator will create an animated text header for your website. This Note analyzes potential problems with the use of MathML for the presentation of mathematics in the notations customarily used with Arabic, and related languages. The goal is to clarify avoidable implementation details. European languages and scripts. European languages. Indeed, most of these. However, there are variations introduced. Math. ML should accommodate for improved international support (in particular educational. While European languages are written left to right (LTR), Arabic, among others, is.
Links to websites where you can download fonts for many different alphabet and writing systems.RTL). We will see that in Arabic mathematical texts many of the. The mathematical directionality is not necessarily the same as the text directionality. Moreover, since the mathematical material may commonly contain text and symbols coming from. Arabic and European languages, the question of how the Unicode bidirectional algorithm. Unicode. Bi. Di] should be applied arises. Finally, several additional symbols and writing styles may be used in special ways. Arabic Calligraphy is enriched by a variety of writing styles. European writing benefits from a variety of fonts. The graphic above illustrates. Arabic calligraphic styles; each word is the name of the corresponding style. In the same way that European mathematics broadens the set of distinct symbols available by. Fraktur or other styles, so does Arabic mathematics but typically. A given piece of mathematics marked up in. Content Math. ML. Math. ML2. 2e], chapter 4), is generally language- neutral — although the. A given piece of mathematics marked up in. Presentation Math. ML. ([Math. ML2. 2e], chapter 3). That appearance. necessarily targets a specific language and notational conventions, indeed even of. In this Note, we amplify and formalize this segregation of concerns. Presentation Math. ML should be a fairly literal. We relegate all localization issues. Presentation Math. ML. rather than the renderer. This avoids guessing, perhaps wrongly, what number is. Thus. localization entails the choice of what. Math. ML's token elements, but that choice is already fixed. Presentation Math. ML. In this Note, we have attempted to examine all notational conventions in current. Arabic and languages written using Arabic script, without giving preference. We aim to clarify the specification of Math. ML, proposing extensions where needed. Math. ML has the broadest coverage possible. Nevertheless, an in- depth analysis of issues. The emphasis on Arabic languages is partly a reflection of an increased interest in, and. Math. ML in Arabic language contexts that have highlighted the issues described here. Another topic for future study is how Content Math. ML might best support the transformation. Presentation Math. ML. 2 Some Features of Arabic Script. Before delving into mathematical notations, it will help to describe some. Arabic script, and how Unicode deals with these features. Text Direction. While European languages are written from left to right (LTR), Arabic is written from. RTL). Unicode supports these scripts by not only defining codepoints. When a mixture of LTR and RTL characters appear in text (ie. Bi. Di text. such as an English text that includes Arabic words). Unicode's bidirectional algorithm [Unicode. Bi. Di] describes the order in which. All adjacent strongly- typed RTL characters (such as a. Arabic word) will be presented in right- to- left order, and vice versa for. LTR characters. A cluster of characters with the same directionality. Within any given "paragraph", directional runs are then ordered according to the. The bidirectional algorithm allows for higher- level. For example, in HTML block- level elements are taken as the. The top- level html tag determines the directional context. For a gentle introduction to bidirectional text, see. Unicode. Bi. Di. Intro]. Glyph Shaping. As Arabic is a calligraphic script, letters within words are typically joined together. When text in such calligraphic scripts is specified by character sequences, a. In Arabic words consisting of a single character, that character is drawn in the "isolated". In multi- character words, alternative shapes are generally used depending on position. Compare the isolated characters غ ي ر. Mirroring. Some characters, viewed abstractly, have the same meaning in many languages. RTL languages are the roughly the mirror image of the. LTR languages. Parentheses and quotation marks are such characters. Unicode deals with these cases by marking some codepoints as mirrored, meaning. RTL context. Note that mirrored symbols are not required by Unicode (See. Unicode. Bi. Di], section 6) to be literally. Indeed, it is considered an important point of Arabic calligraphy. The writer holds the pen so that. This orientation is kept throughout the process of drawing the character. Furthermore, as Arabic writing goes from right to left, some boldness is produced. Thus, the Arabic sum symbol . Number Systems. There are several decimal numeral systems in use in Arabic: 3 Comparison of Mathematical Notations. We will explore the spectrum of notations by choosing some samples of mathematical. We begin with an expression formatted as it might be seen in both English. French contexts. Structurally, the expressions are identical. The differences in names. They are effected purely by. Math. ML token elements. In the following sections, we will examine three common styles used. Arabic texts. The terms Moroccan, Maghreb and Machrek will be. Arabic Notation; Moroccan Style. The current way of writing mathematical expressions in Morocco. French style: Although the mathematics would be embedded within a RTL language (Arabic). LTR. The connecting words and phrases within the math, however. RTL Arabic, and should be subject to glyph shaping. Math. ML renderers are not doing this). Thus these phrases should appear as. Also, the indication is that the bidirectional algorithm [Unicode. Bi. Di] should be. HTML. that is, the token elements act as paragraph segments. Even with these considerations, the ordering of phrases within the last clause. The obvious markup sandwiching. A correct rendering seems to require the possibility. Math. ML 2. 0. But even then, the desired ordering would need to be marked up as two separate mtext elements. The Math Interest Group is currently. The example above was marked up by. Arabic word for "with" after the "pi=3. Given such issues, it is sometimes advantageous to minimize the use of. Arabic Notation; Maghreb Style. The Maghreb style of notation is widely used in North Africa: Here, the most striking difference is that the overall mathematical. RTL. Further, some symbols. Thus, we need a means of specifying the mathematical directionality. Unicode and are marked as mirrored. The remaining differences are due to a more pronounced use of Arabic symbols. DAL (as the initial. Arabic). the Arabic letter BEH . Again, these differences fall into the category of localization. Unicode bidirectional algorithm, along with glyph shaping, should apply individually. Additional Arabic Notations. Two additional unique notations involve combinatorics, namely the factorial and. The argument to the factorial must be wrapped in a form similar to the. LAM (ل), which must. A new menclose notation. Finally, although stacked fractions are rendered the same way in both European and Arabic. RTL Arabic will appear, as one would expect, with the terms in RTL order. A divided by B would appear as "B/A". In some locales, the preference is for the slash to also be mirrored, as "B\A". For these cases. we suggest that authors employ explicit markup using the REVERSE SOLIDUS \, such as. A< /mi> < mo> \< /mo> < mi> B< /mi> < /mrow>. Persian. Persian languages generally use the Arabic script (written RTL), but with. LTR, similar to the Moroccan style. We are aware of only one mathematical notation unique to Persian writing, the notation used. While the overall notation is similar to the Moroccan model (LTR), it uses the. Eastern Arabic- Indic digits. The word "حد" (for "limit"), is. Proposals and Clarifications. Clarification of bidirectional Algorithm for Math. MLThe following summarizes how directionality should be applied to Math. ML. and, in particular, describes how the bidirectional algorithm should be applied. HL4; See Higher Level. Protocols: HL4 in [Unicode. Bi. Di], section 4. The overall mathematical directionality should be determined by. If this attribute is rtl the layout of all Layout, Script, Limit. Table and Matrix schemata should proceed from right to left. This includes. such effects as the surd of an mroot starting from the right. When the mathematical directionality is ltr, the layout should conform. Math. ML specification. The text content of each Token element should be treated as a separate. The initial directional context for each Token element is determined. This latter property should assure that. As an example, consider the Math. ML fragment. < mn> 1< /mn>. Some browsers mis- apply the bidirectional algorithm to the expression as a whole, as in HTML. Applying the HTML algorithm would set the first two items LTR, but then switch directions upon. Glyph Shaping. Glyph shaping rules apply not only to the textual content of an mtext. Arabic character sequences used as mathematical symbols (particularly in. This shaping is the visual cue that. This is analogous to the use of roman font in European mathematics, to distinguish for example. Math/Math. ML" display="display"> < mi> sin< /mi> < /math>. Math/Math. ML" display="display"> < mi> s< /mi> < mi> i< /mi> < mi> n< /mi> < /math>. Thus, implementors should apply shaping to each character sequence within the text content of. Certain Arabic characters (ا د ذ ر ز و). Their use in the middle of a mathematical symbol. Thus, to avoid confusion, authors should avoid using these characters. Additional Mathvariants. For single character tokens, additional styles, besides isolated, are used. Fraktur styles are. European mathematics. The styles used in Arabic mathematics.
