@paramin keysym The keysym.
@paramout buffer A buffer to write the UTF-8 string into.
@paramin size The size of buffer. Must be at least 7.
@returns The number of bytes written to the buffer (including the
terminating byte). If the keysym does not have a Unicode
representation, returns 0. If the buffer is too small, returns -1.
This function does not perform any @ref keysym-transformations.
Therefore, prefer to use xkb_state_key_get_utf8() if possible.
Get the Unicode/UTF-8 representation of a keysym.
