Peter,
VNC 4.1.1 has no such function as removeNonAsciiChars(), replacing it
instead with removeNonISOLatin1Chars(), specifically in order to support
accented characters. The problem you are seeing is a known bug in VNC
4.1.1, caused by comparing a signed char with ISO-8859-1 character values,
which are unsigned. Replacing the removeNonISOLatin1Chars() function with
the following will fix the problem:
void
removeNonISOLatin1Chars(char* text) {
int len = strlen(text);
int i=0, j=0;
for (; i<len; i++) {
unsigned char c=text[i];
if (((c >= 1) && (c <= 127)) ||
((c >= 160) && (c <= 255)))
text[j++] = text[i];
}
text[j] = 0;
}
removeNonISOLatin1Chars() MUST be called in order to ensure that a
viewer/server is does not attempt to send clipboard contents that have
non-ISO-Latin-1 characters, as required by the RFB protocol.
