rlm_sql and UTF8 encoded strings

Hello, I have a problem with german umlauts in Acct-(Multi-)Session-Id. RFC2866 states that the string should be UTF8 encoded which it is. But the sql_escape_func of rlm_sql does not account for utf characters and iterates the string byte by byte. What approach would be best here? Regards Stephan -- i. A.
