Subject RE: [firebird-support] FB 3.0 Replacing ICU libraries
Author Magnus Johansson

Mark, I wholeheartedly agree with you.


I too tried it with 2.5 but didn't success so I gave up at that time.

From what I have been able to read, the documentation that exists seems to be a mix on both 3.0, 2.x and even 1.5 making it a little unclear.

Especially as README.intl.txt also mentions "you can replace ICU libraries by a complete one found in our site", but I don't remember ever having found anything like that on


Thanks for your input,

I believe this is the correct approach, but I have only tried it once
with Firebird 2.5 and ran into some compatibility issues at that time.
Unfortunately this is - afaik - entirely undocumented.

Personally I'd prefer if Firebird was just released with the full ICU
library instead of the trimmed down version.
