Sorry, I should have actually tried the V5 patch and noticed the compiler warning (harmless though it is). Fixed patch attached.

(file #52906)

The current UTF-8 encoding can emit invalid UTF-8 sequences for out of range unicode values. I have attached patches for both V4 and V5.

The unpatched V4 code also contains clearly incorrect logic for overlong UTF-8 sequences that modern compilers will warn about (which I have removed).
