Unac is a c programmer's library that removes accents from a string. for instance the string ?t? will become ete. it provides a command line interface that removes accents from a input flow or a string given in argument (unaccent command). in the library function and the command, the charset of the input is specified as an argument. the input is converted to utf-16 using iconv(3), accents are stripped and the result is converted back to the original charset. the iconv --list command on gnu/linux will show all charset supported.
