[XeTeX] TECkit map for Latin alphabet to Unicode IPA

[Daniel Greenhoe]

Is there already a TECkit map available to map the Latin alphabet
(abc...) to Unicode IPA code points,
where the Latin symbols are defined by tipa 1.3
(http://www.ctan.org/pkg/tipa) and
where the Unicode IPA code points are as defined by the Unicode
standard (http://unicode.org/charts/PDF/U0250.pdf)?

Many thanks in advance,
Dan
