  Mathematical Alphanumeric Symbols - Test for Unicode support in Web browsers
The Mathematical Alphanumeric Symbols range was introduced with version 3.1 of the Unicode Standard and is located in Plane 1 (the Supplementary Multilingual Plane), which requires the enabling of surrogates in Windows 2000; these characters cannot easily be displayed in earlier versions of Windows.
Other mathematical symbols can be found in the Miscellaneous Mathematical Symbols-A and Miscellaneous Mathematical Symbols-B ranges.
The characters that appear in the “Character” columns of the following table depend on the browser that you are using, the fonts installed on your computer, and the browser options you have chosen that determine the fonts used to display particular character sets, encodings or languages.

Mathematical alphanumeric symbols are modifications of Latin and Greek letters and decimal digits that enable mathematicians to denote different notions with different letter styles (one example is flboard bold, or double-struck (in Unicode terminology)).
The rationale behind this is that it enables design of special mathematical fonts that include all necessary characters in a single collection.
Those symbols should be used only in mathematical formulas; in general text, use standard letters with markup instead.

 Astral Planes
As the TLG proposal on these symbols makes clear, there is abundant variation in the glyphs used to represent the various values, and modern editors have made no attempt to impose a standard.
Mathematics as a system is the great interloper, wrenching characters out of their typographical context and using them with completely different semantics, as mathematical terms.
In Mathematics, then, shifts of typeface, script, and style are important enough to yield completely distinct meaning: the difference between a script and a flletter H is rather more grave in Mathematics than it is in normal textual use of the Latin script.

 UTR #25: Unicode and Mathematics
Mathematical Markup Language (MathML™) [MathML], an XML application [XML], is a major beneficiary of the increased repertoire for mathematical symbols.
Mathematical symbols with diacritics are always represented by combining character sequences, except as required by normalization.
The latter is the symbol for the Weierstrass elliptic function, a calligraphic letter shape based on the small p, and the former is derived from a special italic letter shape called an 'ell', and is unified with the common non-SI symbol for the liter [SI].

 Table of mathematical symbols Summary
It is difficult to understate the importance of mathematical symbolism on both the field of mathematics and on the other fields that use mathematics.
All of these symbols, mathematical included, depend on recognition to succeed; a person unschooled in mathematics will see π simply as a Greek letter or, depending on their educational background, as simple a grouping of three lines.
The symbols introduced by Euler are among the most important and most commonly used symbols in mathematics, but they are also among the most important in many other fields that depend on mathematics.

 DATE: 1998-12-01
Accurate publication of mathematical and scientific research on the Web is impossible without a comprehensive and accurate collection of symbols including various alphabetic variants in common use.
Mathematics has need for a number of Latin and Greek alphabets that on first thought appear to be font variations of one another, e.g., normal, bold, italic and script H.
However, while technically feasible for the representation of the required mathematical alphabets, the encoding of such math style variant tags raised unanswerable questions regarding what would happen if they were applied outside their intended mathematical domain--for example, to accented Latin letters, or even to other scripts such as Han characters.

 Characters, Entities and Fonts
Many letter-like symbols may be quickly interpreted by specialists in a given area as of a certain mathematical type: for instance, bold symbols, whether based on Latin or Greek letters, as vectors in physics or engineering, or fraktur symbols as Lie algebras in part of pure mathematics.
The exact correspondence between a mathematical alphabetic character and an unstyled character is complicated by the fact that certain characters that were already present in Unicode are not in the 'expected' sequence.
Mathematical Alphanumeric Symbol characters should not be used for styled text.

 Interloping Scripts
The Greek symbols used do not have the same appearance they would in a normal Greek font: their shapes have been modified to harmonise in a Latin context (since letters from both scripts appear in the same word).
There isn't the risk of misuse that there is for the mathematical symbols, because there are only five uppercase and five different lowercase characters involved, and they aren't as immediately usable as bold, italic and monospace.
The mathematical typesetting of Greek letters in an overall Latin context has developed its own tradition, which Haralambous (§2) spends a little time discussing; it includes the obligatory italicising of Greek, and the preference for closed phi and theta, and distinctive glyphs for alpha and gamma.

The proposals for mathematical alphanumerics and for mathematical and technical symbols were discussed at the October 26-29 meeting of the UTC.
The proposal Request for assignment of codes to mathematical and technical symbols (L2/99-244R) has been revised; this version will be considered at the October 26-29 meeting of the UTC.
The proposal entitled Request for assignment of codes to mathematical and technical symbols (L2/99-244) has been updated in response to a review by several UTC members, and will be carried into the semiannual Unicode Conference for additional feedback.

The presence of the ‘math alphanumeric symbols’ characters (in plane 1) is one of the reasons for the Swedish NO vote on the 10646-2 CD.
The current proposal for math “alphanumeric symbols” covers essentially only A-Z (and basic Greek), while programming language identifiers are being generalised to allow for any written “word” in a natural language.
Note that in some areas of mathematics it is common to use multi-letter identifiers, often taken from words in a natural language.

The result is that mathematics makes use of a very large collection of symbols.
When you look carefully at the range of letter-like mathematical symbols in common use today, as the STIX project supported by major scientific and technical publishers did, you come up with perhaps surprisingly many.
The detailed correspondence is shown in the tables given in Section 6.3.6 Mathematical Alphanumeric Symbols.

 Arabic mathematical notation
A given piece of mathematics marked up in Content MathML ([MathML22e], chapter 4), is generally language-neutral — although the choices for variable names may imply a cultural context — it intends to represent the universal meaning of the mathematics.
Note that the symbol used for summation should probably be a mathematical symbol with a codepoint distinct from the Arabic letter, as the European summation symbol is distinct from the Greek Sigma.
Even though some local symbols, used in mathematics written in an Arabic notation, can be obtained via mirroring of already existing symbols, there are many symbols found in Arabic mathematical handbooks that are not yet part of the Unicode Standard and cannot be obtained through a simple mirroring [ArabicMathUnicode].

 Sorting It All Out : For those who enjoy mathematics (or, 'Also new in Vista')
My favorite range is the Mathematical Alphanumeric Symbols block in Unicode, which currently has all of the characters from U+1d400 to U+1d7ff (almost 1000 in all, with some spaces that were left in, as you can see from the code chart).
Also, a URL with a mix of mathematical and Latin characters might not be flagged up as a URL containing characters from multiple languages because, in a sense, it doesn't.
The mathematical alphanumerics, particularly the serifed italic, bold, bold italic, script, and Fraktur sets, are proving to be very useful in a math display and editing system some of us are working on.

The subject naturally has a close relationship with the discipline of financial economics, however the subject is narrower in scope and more abstract.
A central difference is that whilst a financial economist might study the structural reasons why a company may have a certain share price, a mathematician may take the share price as a given, and attempt to use stochastic calculus to obtain the fair value of derivatives of the stock."
