A string with a single byte that has high-bit set (characters 128-255)
is *not* a valid UTF-8 sequence. That's why you get the error. One could
argue that chr(146) should throw an error right away, since 146 doesn't
represent a valid ASCII character either.
In fact, this has been changed in the CVS; in the upcoming 8.3 version,
chr(146) in UTF-8 encoding will return a two byte character
corresponding the unicode code point 146, which seems to be a control
character, marked for "private use only".

That's quite an exaggeration, don't you think? As a work around, don't
put invalid data in your database. Don't use chr-function, it's really
only there for compatibility with other DBMSs that has it.
