The good news is that LiveCode 7 will not have this problem, but it still might sneak in if one is not careful.
With LiveCode 7, the codePoint chunk will apply even to U+1F4DE (a new character, I guess, for a phone?), that is, 128222. However, if you look at the implementation level, the codeUnit, you will see the two numbers you describe. These are surrogates, away for 16-bit representation to include characters above U+FFFF, or outside the BMP. So to represent those high codes, two 16-bit codes are used. These are assigned but never occur in LiveCode 7 code points, only in the implementation code units. So, if you’re working with characters or code points, you are good. With 7. For now… There is a way to calculate the full code from the surrogates. Take the least significant 10 bits of the first number, add 0x40 and then shift left 10 bits. Add that to the least significant 10 bits of the second number. Stand on one foot and... It is probably someplace online in a clearer form.
