Unicode LaTeX

Provides maps between unicode symbols and LaTeX commands.

• latex-unicode.json map from latex to unicode.
• unicode-latex.json map from unicode to latex.
• unicode-latex.sty LaTeX package for using α instead of \alpha for improved readability of math commands.

This package strives to cover all symbols and to use standard LaTeX commands, e.g. \mathbb{C} instead of \BbbC, in contrast to other unicode packages (e.g. unicode-math and Julia).

Please open an issue if you see something missing/wrong.

Updating

The file latex-unicode.json is the source, from which unicode-latex.json and unicode-latex.sty are generated with generate.py.

To do

Currently there is no support for subscripts and superscripts in the LaTeX packge. This cannot be done trivially by mapping ¹ to ^1 because then sub/superscritps cannot be joined (^1^2 gives latex error "double superscritps"). The solution should be to parse unicode sub/superscripts like unicode-math does.

Sublime Text unicode input

The package InstantUnicode provides easy input of unicode symbols, it uses latex-unicode.json.

Other notes

• There may be multiple LaTeX commands mapping to the same unicode symbol, e.g. both \iff and \Longleftrightarrow maps to ⟺.

• In the LaTeX package unicode-latex.sty the italic unicode symbols, e.g. 𝑎 are normalized to a, since a already renders as italic in math mode.

• The files where originally generated from the file unicode-math-table.tex with the script generate_old.py which standardized and normalized the data, and added some missing symbols and synonyms. After this I have started to make manual changes to the files, to fix errors in the original files.
