UTF8

Oct 11, 2011 Mature
Provides UTF-8 aware string functions implemented in pure lua: string.utf8len(s) string.utf8sub(s, i, j) string.utf8reverse(s) If utf8data.lua (containing the lower<->upper case mappings) is loaded, these additional functions are available: string.utf8upper(s) string.utf8lower(s) All functions behave as their non UTF-8 aware counterparts with the exception that UTF-8 characters are used instead of bytes for all units.
