Yes.

BTW, I have databases in WIN1250 format, shared between Linux, Windows
and web clients and everything works fine (running in production on
Firebird 1.0, 1.5 and 2.0)

PHP processes the data as-it, i.e. as user typed it. You need to make
sure that your HTML pages contain ISO8859_1 charset meta tag (in HEAD
section), otherwise you'll see such errors. When HTML page is marked as
ISO8859_1 the web browser does transliteration between the user's
environment and ISO8859_1.

If you left all your HTML pages charset undefined, it depends on the
browser (what does it auto-detect) so you might get UTF8 from Linux
clients running Firefox, and ISO8859_1 from Windows clients running IE, etc.
