[bug-gnu-libiconv] Mapping of U+0385 in CP1258 is likely incorrect

[Gertjan Halkes]

Hi,

U+0385 (GREEK DIALYTIKA TONOS) is currently mapped to A5 EC (maps to Unicode
YEN SIGN and COMBINING ACUTE ACCENT) in CP1258. However, based on the
cannonical decomposition specified in unicode, the conversion should most
likely be A8 EC (DIAERESIS and COMBINING ACUTE ACCENT). Note that this mapping
is already used for U+1FEE (GREEK DIALYTIKA AND OXIA) which is specified to be
equivalent to U+0385, confirming the mapping to A8 EC.

Note that the reverse mapping is also present and should be changed as well
(or removed because of the duplicate mapping to U+1FEE).

Regards,
