That is strange. There should be no multibyte characters other than
Japanese. German umlauts are ISO-8559-1 and thus 8-bit.
Are you sure that nightcats_ii_en_de.cdt has the correct charset?

cdtext_set calls cdio_charset_to_utf8 (line 477) which calls iconv. The
code is in utf8.c.

Correct. I am going to implement it, though. Give me a couple of days.

My bet is, that this comes from the encoding issue where iconv fails.
Please double check if the charset-bits really say ISO-8859-1 and if
the ä's are correctly encoded. The double byte bit must be 0.

I could look into this once I have the time.
