Enable accent for east European characters (Win 1250)

[Marek]

Enable accent/diacritic/ligature insensitivity doesn't seem to work quite correctly in handling character "č" of Slovak alphabet. Do you know how to improve this?

[Ray]

Since the "diacritic insensitivity" feature is designed to be used for a number of different languages, we could not add support for the c-caron ("č") character here due to the way it conflicts with some of the other character sets. This would most likely require a separate feature all together. We currently do not have plans to add this feature in the immediate future. If others find this important, drop us a note.
