The scanner uses the utf8 encoding of files as it looks now, so it has 
no concept of bytes. Which means grapheme clusters. I think that's the 
only sensible approach.

The combining characters... Hmmm... We could translate them to their 
proper code points too, but we only do that for file names now... Let me 
get back to you on that one :)
