Samuel Thibault cc3519b818 speakup: Fix 8bit characters from direct synth ... [ Upstream commit b6c8dafc9d ] When userland echoes 8bit characters to /dev/synth with e.g. echo -e '\xe9' > /dev/synth synth_write would get characters beyond 0x7f, and thus negative when char is signed. When given to synth_buffer_add which takes a u16, this would sign-extend and produce a U+ffxy character rather than U+xy. Users thus get garbled text instead of accents in their output. Let's fix this by making sure that we read unsigned characters.
