No, you confuse two things here.

First, xmlUTF8Strlen() only knows the UTF-8 encoding. It knows nothing
about Latin-1 or other encodings. As your string is a valid UTF-8
encoded string, xmlUTF8Strlen() will return the length of the entire
string -- not the number of characters which cannot be encoded in
Latin-1, which would be necessary for your scheme to work.

Second, xmlUTF8Strlen() returns the number of characters, not the number
of bytes.

What you need to do is to skip ahead one UTF-8 encoded character yourself,
and then continue processing. Have a look at the code for xmlUTF8Strlen()
to get inspiration on how to skip one UTF-8 encoded characters.
