Is the expected output

   å å (å) Å Å (Å) æ æ (æ) œ œ (œ) Æ Æ (Æ) Œ Œ (Œ) ø ø (ø) Ø Ø (Ø) ß ß (ß)

(width 74) or

   @aa å (å) @AA Å (Å) @ae æ (æ) @oe œ (œ) @AE Æ (Æ) @OE Œ (Œ) @o ø (ø) @O Ø 
(Ø) @ss ß (ß)

(width 90)?

I guess you will need to look at the Unicode characters that you pass to 
c32width,
and whether you get return values < 1 for some of them.
