It doesn't but if the given line is changed to
hyphen_string = create_string_buffer(inlen.value+2)
then it works on all words in my document.
I guess you can explain this if liblouis doesn't handle inlen properly.
The input string probably has 16 bit characters on this system
(including the NULL character), so the NULL character is 2 bytes. We
should use:
inlen.value + sizeof(c_wchar)
I think this is really a bug in liblouis, though. The documentation says
the output buffer must be of size inlen, so it shouldn't write past inlen.
