Hi Saf,

you could try to use the resource <http://www.w3.org/2003/entities/2007xml/unicode.xml>  from

XML Entity Definitions for Characters

W3C Recommendation 01 April 2010


the "master file detailing all Unicode characters with names in various entity sets and applications, TeX equivalents and other data".

It is an XML file maintained by the W3C that contains both the entity names and corresponding latex macro names (although its not clear for which LaTeX packages).
With a simple xslt you could extract the mapping you are looking for.

Regrads,
Chris
