NAME
TeX::Encode - Encode/decode Perl utf-8 strings into TeX
SYNOPSIS
use TeX::Encode;
use Encode;
$tex = encode('latex', "This will encode an e-acute (".chr(0xe9).") as \'e");
$str = decode('latex', $tex); # Will decode the \'e too!DESCRIPTION
This module provides encoding to LaTeX escapes from utf8 using mapping tables in Pod::LaTeX and HTML::Entities. This covers only a subset of the Unicode character table (undef warnings will occur for non-mapped chars).
Mileage will vary when decoding (converting TeX to utf8), as TeX is in essence a programming language, and this module does not implement TeX.
I use this module to encode author names in BibTeX and to do a rough job at presenting LaTeX abstracts in HTML. Using decode rather than seeing $\sqrt{\Omega^2\zeta_n}$ you get something that looks like the formula.
The next logical step for this module is to integrate some level of TeX grammar to improve the decoding, in particular to handle fractions and font changes (which should probably be dropped).
CAVEATS
Proper Encode checking is not implemented.
encode()
Converts non-ASCII Unicode characters their equivalent TeX symbols (unTeXable characters will result in undef warnings).
decode()
Attempts to convert TeX symbols (e.g. \ae) to Unicode characters. As an experimental feature this also handles Math-mode TeX by inserting HTML into the resulting string (so you end up with an HTML approximation of the maths).
