Thread: pgAdmin2 UTF-8 support
Dear friends, PostgreSQL 7.2 offers extensive UTF-8 support. In case of an UTF-8 database, the big news seems that we now have to write function and view definitions in UTF-8. The problem is that pgAdmin2, HighlightBox (the colour code editor) and the result view do not support Unicode by now. And probably will not whithout further information. Questions : 1) Is it possible to convert functions/views to/from UTF-8/SQL_ASCII using server-side queries in PostgreSQL. $M cowboys do not offer tools to convert Unicode on the fly in VB. Is there something in PostgreSQL? to_ascii can convert from unicode to ascii. How can we do the converse? 2) Do you know if ODBC UCS-2 support would help us with pgAdmin2? Does anyone has extensive knowledge of UCS-2 support under VB? As far as I know, VB only supports reading UCS-2 files and displaying data in Hflexgrid. Any idea welcome, Cheers, Jean-Michel POURE
Jean Michel We have a Unicode hebrew db in PG7.2. Uou dont need to write the functions and views in UTF-8 unless you have some literals inside the code. We had this issue with Hebrew; so we store all the literals as tokens in another table which may have some overhead but makes for great flexibility. None of our functions or views are coded in UTF-8 and they work just fine. If you have some functions that MUST be in UNICODE you might define them as triggers so that when VB does an action on the PG db - the trigger fires - that should give you transparent operation to VB. FWIW - the gnu recode function converts anything to anything. It can run on the server side - for example in plpgtcl procedures. BTW - you probably all know this but if you really want ORDER BY to work in Unicode - you should use glibc2.2 - ie. RH72.

In PostgreSQL 7.2 we found it was possible to SET CLIENT ENCODING TO LATIN1 and display data from a unicode database without problem (with French hyphens éèù, etc..). This was not possible in 7.1.x. It would of great help for us if you could install pgAdmin2 (http://pgadmin.postgresql.org) and do the following test. - connect to your UTF-8 database, - Enter SET CLIENT_CODING TO one of the following available at http://www.postgresql.org/idocs/index.php?multibyte.html. Maybe there are new encodings available. Recode can translate nearly all encodings. Can you see the Hebrew information? What font should be used for displaying Hebrew information in pgAdmin2? Could you send us a sample Hebrew table_dump (10 records). Cheers, Jean-Michel
Dear Danny, Could you try pgAdmin2 and enter 'SET CLIENT_ENCODING = ISO-8859-8'. Then try to display data in pgAdmin2. Does it work? Information can be found at http://developer.postgresql.org/docs/postgres/multibyte.html#AEN16680 Cheers, Jean-Michel POURE
