I think what Jan is alluding to is the property of UTF-8 text that you 
can start in the middle of a string and either skip an incomplete 
character or find the beginning of it.  If you can search backwards, you 
can find the beginning of an escape sequence, too; the "skip incomplete" 
 functionality is missing, though, but as you say, isn't actually all 
that useful in real life *for the applications which use these kinds of 
escape sequences.*
