| I found when testing my Unicode enhancements to MUSHclient that a heap of things would not work correctly. For instance, typing:
think (some Unicode string)
would result in the MUD replying:
Think what?
A bit of research led to the following lines in function read_from_buffer in comm.c ...
if ( d->inbuf[i] == '\b' && k > 0 )
--k;
else if ( isascii(d->inbuf[i]) && isprint(d->inbuf[i]) )
d->incomm[k++] = d->inbuf[i];
This seems to be discarding any input that is not 7-bit ASCII, and is also redundant - why check for "isascii" AND "isprint"?
I suggest this change:
if ( d->inbuf[i] == '\b' && k > 0 )
--k;
else if (isprint(d->inbuf[i]))
d->incomm[k++] = d->inbuf[i];
This lets printable characters through, which is what you really want.
After making that change you could "think" or "say" Unicode strings.
