Re: [Haskell-cafe] very strange utf8 problem

Hi all,

I know this sounds daft but I do have good reason to ask.

Is it possible that GHC's core itself has a problem with a particular Umlaut only?

HDBC-ODBC won't read in data from an SQLite database as soon as it comes accross a *lowercase* U-Umlaut ("ü") ghci crashes. Other Umlauts ("ä", "ö" and "ß") pass however.

This is the error message:

 readUTF8Char: illegal UTF-8 character 252

As I said, other Umlauts do pass.

I suspect something is trying to read ISO-Latin-1 data as UTF-8. 252 is the Unicode and Latin-1 code point for "ü", but in UTF-8 it's written in two bytes as 0xC3BC. -- Dave Menendez http://www.eyrie.org/~zednenem/
