from ascii to hex for unicode char

[Jelle Huisman <jelle@...>]

Hello,

I try to analyse a unicode character, e.g. "ည". I am able to get the 
ascii code for this string using: print(utf8.byte("ည",1,-1))
This gives me 4106, which is correct. However I would like to get the 
unicode codepoint in hex notation, for this character this would be: 
0x100A  How do I get this result? (I use the slnunicode library)

Thanks,

Jelle
