(sample sent offlist)..

I've been looking at your code myself to see if I could help and tracked down 
your output line (in v0.7.0) to

swfextc.c:466
                printf("%c", code);

which is obviously only going to work for ascii codes up to 127 since UTF8 is 
variable length and probably needs a %lc passed a wchar_t. All of this is new 
to me so I'm not sure if it's obvious to others or not who might also find it 
interesting. I've never really hacked on this sort of code before.


I thought you might find this information helpful for UTF8 output:

UTF-8 encoding is variable-length, and characters are encoded with one, two, 
three, or four bytes. The first 128 characters of Unicode (BMP), U+0000 
through U+007F, are encoded with a single byte, and are equivalent to ASCII. 
U+0080 through U+07FF (BMP) are encoded with two bytes, and U+0800 through 
U+FFFF (still BMP) are encoded with three bytes. The 1,048,576 characters of 
the 16 Supplementary Planes are encoded with four bytes.
