Firebird INTL Architecture

Peter Jacobi has made available a new version of fbintl2.dll at http://www.jodelpeter.de/i18n/fbarch/ (example, source, Win32 binary, sample scripts), along with more information and a download to test. New features include: Some defective handling of trailing spaces in comparisons have been fixed. The very interesting case of the Thai character set TIS 620 and its sorting according to the Thai Royal Dictionary, has been included for testing. Also a first attempt to make the multi-level collations more space efficent. Whereas current Firebird uses 24 bits/character, the TIS620_TH_TH collation is happy with 10 bits/character, for a full fledged four level collation.
