I think my current PostgreSQL database being UTF-8 is factoring in with the problem, probably the FDW reads the data with the encoding it's given alright, but it makes no diference since the database gives the data in UTF-8 when I query it anyway which does not fit the stored bytes. I have forced the variations I could find for LATIN1 in encnames.c from witch libfq takes the encoding names to no avail. (I've put my test strings above in an image to avoid people names ending up on the search for this PR and biting me on the ass in the future) PSQL will just ignore the character and show the rest of the string, like this query for the name of the contact: The most common example of this is storing 8bit data in a SQL_ASCII database." This is most likely caused by stored data containing characters that are invalid for the character set the database was created in. To see if maybe I could try and implement a flag to force the encoding on the connection,ĭBEAVER will show the following exception on the collumn: "DBCException: SQL Error : Invalid character data was found. Val = GetDatabaseEncodingName() to val = 'LATIN1' or val = 'ISO8859-1' ![]() I'm still trying to fix this to avoid having to deal with the conversion in the future, I tried forcing LATIN1 or ISO8859-1 (and even NONE since it's the original fb database's default) into the client_encoding on firebirdGetConnection() inside connection.c, by changing the lines: I've set up the data wrapper and have been querying the database for almost 3 months now, so it works but I had to write the queries converting every varchar to ISO-8859-1 with convert_from(COLUMNNAME::BYTEA, 'ISO8859-1') which is annoying but works fine for me for now. I'm using this firebird_fdw to query data from a database for which I have no control over how the data is stored nor it's structure, also I'm not a C developer, I can compile libs and understand the code, but not much else. ![]()
