Converts simple LaTeX to an unicode approximation
Project description
Convert simple LaTeX into an unicode approximation and paste it anywhere.
This package provides a more complete LaTeX to Unicode converter than unicodeit. unicodeitplus uses a better parser (generated from EBNF with the fantastic Lark library) than unicodeit, which handles some code on which unicodeit fails, and allows one to parse a mix of text and math code, like:
$p_T$ / GeV $c^{-1}$
I want to eventually merge this project into unicodeit, discussions with the maintainer of unicodeit are ongoing.
LaTeX to Unicode: How does this even work?
Unicode contains many subscript and superscript characters. It also contains font variations of characters of both latin and greek characters, including italic, boldface, bold italic, and more. It contains a lot of special mathematical characters and diacritical marks, which we use to approximate LaTeX renderings using just unicode characters.
Like unicodeit, unicodeitplus is largely based on unimathsymbols.txt from Günter Milde, which provides the mapping between LaTeX macros and Unicode symbols.
Caveats
Only a subset of all LaTeX code can be converted to Unicode. Some Unicode characters simply don’t exist. For example, subscript characters exist only for a subset of all lowercase latin characters, there are no subscript characters for uppercase latin characters, and all subscript or superscript characters are in roman font (upright).
Some code is rendered the best best approximation, for example, p_T as 𝑝ₜ, assuming that a reasonable approximation is preferred over a failed conversion.
Your font needs to contain glyphs for the Unicode characters, otherwise you will typically see a little box with the unicode character index.
The visually best results seem to be obtained with monospace fonts.
