NAME
TeX::Encode  Encode/decode Perl utf8 strings into TeX
SYNOPSIS
use TeX::Encode;
use Encode;
$tex = encode('latex', "This will encode an eacute (".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 nonmapped chars). This module is intentionally vague about what it will handle, see Caveats below.
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).
METHODS
 TeX::Encode::encode STRING [, CHECK]

Encodes a utf8 string into TeX. CHECK isn't implemented.
 TeX::Encode::decode STRING [, CHECK]

Decodes a TeX string into utf8. CHECK isn't implemented.
 TeX::Encode::perlio_ok

Returns 0. PerlIO isn't implemented.
CAVEATS
Proper Encode checking is not implemented.
LaTeX comments (% ...) are ignored because chopping a lot of text may not be what you actually want.
encode()
Converts nonASCII Unicode characters to 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 Mathmode TeX by inserting HTML into the resulting string (so you end up with an HTML approximation of the maths  NOT MathML).
