 Description  « Hide
When an attachment using NONE charset uses non-ASCII characters that go to MON$ tables, selects from MON$ tables (in other attachments) fail.

The error is about incorrect transliteration (v2.1.X) or malformed string (v2.5).

The problem is that with NONE there is no way to convert strings from unknown charset to system charset, that will be converted later to client charset.

The solution for this problem is to replace (only with attachments using NONE) non-ASCII characters that go to MON$ to question marks.
