And I forgot to say that using a "%c" in printf is _always_ wrong with
UTF-8 text, exactly because of multibyte characters. You should pass
the complete multibyte character (i.e., all its bytes in one CHAR
command) to speechd-up, by making a string out of it (see below how to
determine the number of bytes to be copied) and using "%s" with
printf.

First byte      number of bytes to copy
0x00-0x7F         1 byte
0xC2-0xDF        2 bytes
0xE0-0xEF        3 bytes
0xF0-0xF4        4 bytes
