I'm doing this using DevArt IBDAC, but I get the same using isql. No clue why I can't get the correct text.

In the source, I see the following: begin exception test _utf8 X'31D0A2D095D0A1D0A220D09DD09020D091D0AAD09BD093D090D0A0D0A1D09AD098'; end >3) Validate that RDB$PROCEDURES.RDB$PROCEDURE_BLR (not >RDB$PROCEDURE_SOURCE!) really contains a Unicode string In the BLR, I see: 0502040101000700029B110002028006 // 0454455354150F0400210031D0A2D095 // TEST ... ! then the same as above in hex D0A1D0A220D09DD09020D091D0AAD0 9BD093D090D0A0D0A1D09AD098 FF0E01020115070019014C >4) Connect as WIN1251, execute SP - error text is Cyrillic >5) Connect as WIN1250, execute SP - cannot transliterate character >between character sets When executing the procedure, UTF8/WIN1251/WIN1250 connected, I get: exception 1 TEST 1ТЕСТ ÐРБЪЛГÐРСКИ At procedure 'TEST' line: 4, col: 3 This -could- be my error, but how do I verify?

Or at least, not in my test? I tried without the _utf8 prefix and it worked: 1) Connect as UTF8 charset 2) Create SP with EXCEPTION ERROR 'some Cyrillic string'; 3) Validate that RDB$PROCEDURES.RDB$PROCEDURE_BLR (not RDB$PROCEDURE_SOURCE!) really contains a Unicode string 4) Connect as WIN1251, execute SP - error text is Cyrillic 5) Connect as WIN1250, execute SP - cannot transliterate character between character sets Dmitry

Now, I tried the following in the procedure to work around the above: exception test _utf8 'unicode string here'; When I look at RDB$PROCEDURES.RDB$PROCEDURE_SOURCE I can see the text is inserted as a hex string. But this doesn't seem to work either? Does this work at all with Exceptions?

Historically, RDB$EXCEPTION_MESSAGE has NONE charset, so it's never transliterated to the client charset. The engine simply has no idea that you stored UTF8 there. Sigh. Dmitry
