in reply to Re^6: Sorting Vietnamese text
in thread Sorting Vietnamese text
Any other ideas?A quick search shows that vietnamese words are sorted by letters first, then tone-marks. Sometimes tone-marks are even ignored. So that's probably correct:
ỳ : ỷ : ỳ ạch :http://vietunicode.sourceforge.net/charset/quytacABC_en.html ...looks like Unicode::Collate does it right, but additional first-character ordering is required to get a dictionary order (happens to be different from a simple sorted order in vietnamese).
