Fixes a long-standing bug with glk_buffer_to_title_case_uni() where the results would be incorrect for characters that expand into more than one character in titlecase. We hardcode a list of titlecase exceptions from Unicode, and otherwise continue to use the GLib 1-to-1 mapping from g_unichar_totitle(). Closes: #28

Upper- or lowercasing Unicode strings is not possible by mapping one character to one character in each case, in contradiction of what the GLib functions
g_unichar_tolower()andg_unichar_toupper()would seem to suggest. There is unfortunately no title-casing function in GLib that allows for the title-case of a character to be longer than one character, so we either have to wait for one to be added, or roll our own.The text was updated successfully, but these errors were encountered:
