Map between LaTeX commands and Unicode points - unicode

Question

Is anyone aware of where I could find a table mapping LaTeX commands to Unicode code points? eg: \le is 0x2264. I'm looking for something as comprehensive as possible.

Answer 1

The document I've used before is this XML file from the W3C. It maps Unicode to HTML, MathML, LaTeX, Mathematica, and others. (The file is 1.4 MB, uncompressed.)
You can read more about it here: http://www.w3.org/TR/unicode-xml/

Answer 2

I once cooked up this for a report generator written in Java (hence the Java String literals):
'\\'(REVERSE SOLIDUS) "\\textbackslash{}"
'^'(CIRCUMFLEX ACCENT) "$\\uparrow$"
'_'(LOW LINE) "\\textunderscore{}"
'|'(VERTICAL LINE) "\\vline{}"
'~'(TILDE) "\\textasciitilde{}" "~"
'§'(SECTION SIGN) "\\S{}"
'ª'(FEMININE ORDINAL INDICATOR) "$^a$"
'­'(SOFT HYPHEN) "\\-"
'²'(SUPERSCRIPT TWO) "$^2$"
'³'(SUPERSCRIPT THREE) "$^3$"
'·'(MIDDLE DOT) "$\\cdot$"
'¹'(SUPERSCRIPT ONE) "$^1$"
'º'(MASCULINE ORDINAL INDICATOR) "$^o$"

But I'm pretty sure there isn't a comprehensive mapping anywhere - Unicode is HUGE. You'll probably have to compile and maintain it yourself. Good luck!

Answer 3

Here's a web app based on the data mentioned above: http://www.johndcook.com/unicode_latex.html
Type in Unicode and it looks up the LaTeX symbol and vice versa.

Answer 4

You can check out my LaTeX to Unicode converter. It has a JavaScript API which you can use under MIT license. It is partially based on the W3C document shared earlier, but supports even more mappings that I gathered from here and there.
Most mappings are straightforward table lookups, but some commands have no or ambiguous Unicode equivalents. A comprehensive converter requires creative decisions. For example, fractions are quite complicated. frac{5}{8} produces ⅝, frac{5}{80} produces ‌5⁄80‌ and frac{5}{80a} produces (5 / (80a))).

Answer 5

This is for the Word 2007 Equation Editor but it shares many similar commands with LaTeX: http://unicode.org/notes/tn28/UTN28-PlainTextMath.pdf
This huge table contains Unicode translation to LaTeX, MathML entities and Mathematica: http://www.ams.org/STIX/bnb/stix-tbl.asc98feb26
