Encoding problem

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi List !

I am trying to remove accents from a string. I found a nice solution for this on postgresqlfr, using the to_ascii() function.

Now, the problem I have is :

mydb=# SELECT to_ascii(convert('abcdef', 'LATIN9'));
ERROR:  encoding conversion from UTF8 to ASCII not supported

Why is the conversion to LATIN9 not working as expected ?
My database's encoding is UTF8.


Furthermore, in PgAdmin, running SELECT convert(somestring, 'LATIN9'); returns empty strings whenever somestring contains special (accentued, in my case) characters.
SELECT Length(convert(somestring, 'LATIN9')); looks OK though !

I think my misunderstanding of encoding is driving me crazy...
Could anyone help me on this ?

Thanks !
