If I'm using the provided script string (add on) and I have a string instance (in script) which is has international glyphs (via utf-8).. is there any existing unicode-aware way to get the logical length()? I'm looking for the number of logical glyphs, not the length of the underlying string, per se.

Thanks.

UTF8 is actually quite friendly in this way. Each byte that doesn't have the bits 8 and 7 set to 0b10 is a new glyph.

int countUTF8Glyphs(const string &str)
{
   int count = 0;
   for( int n = 0; n < str.length(); n++ )
   {
      if( (str[n] & 0xC0) != 0x80 )
        count++;
   }
   return count;
}
