Don't use non-ASCII characters in the link.

The link anchor is just a string that is used internally.
It is never displayed in the PDF, so why risk running
into encoding problems by using non-ASCII characters?

PDF does not use UTF8 at all. 
You'll have to transform any UTF8 characters into a UTF16 
ASCII-HeX representation of the Unicode code-point,
both in the destination-label and in any corresponding
hyperlink target-labels that point at it.

Hyperref gives the means to do this, using  \pdfstringdef .

But since this label is only used internally, you might as well
save your self some trouble, and (La)TeX some processing time,
by just using ASCII letters for such things.

Hope this helps,
