So umlauts in the content field of a tag in the bib file seems to be accepted, but not in the key. The behavior is the same whether a numerical or alphabetical reference style is used.

BibTeX cite keys cannot include non-ASCII characters (among other things). Other 7 or 8-bit characters will generally pass through unscathed in the data fields, but may not sort correctly. You can use bibtex8 with some character sets for correct sorting.
