TeX::Encode::BibTeX - Encode/decode Perl utf-8 strings into BibTeX

       Timothy D Brody, <tdb01r@ecs.soton.ac.uk>

       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  non-ASCII  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  Math-mode  TeX  by  inserting  HTML  into  the  resulting  string  (so  you  end up with an HTML
       approximation of the maths - NOT MathML).

       This module provides encoding to LaTeX escapes from utf8 using mapping tables. This covers only a subset
       of the Unicode character table (undef warnings will occur for non-mapped 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).

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

       TeX::Encode::BibTeX::encode_url STRING
           Make a URL safe for inclusion in BibTeX.

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

       TeX::Encode::perlio_ok
           Returns 0. PerlIO isn't implemented.

         $tex = encode('bibtex', "This will encode an e-acute (".chr(0xe9).") as \'e");
         $str = decode('bibtex', $tex); # Will decode the \'e too!
