to_ascii( text )

- encode 'text' from database encoding to ASCII

to_ascii('\256\341k')

to_ascii( text, int4 )

- encode 'text' from 'int4' encoding to ASCII

to_ascii('\256\341k', 8)

to_ascii( text, name )

- encode 'text' from 'name' encoding to ASCII

to_ascii('\256\341k', 'LATIN2')

Now is supported LATIN1, LATIN2, WIN1250. For other character sets I
haven't good resources. Add new encoding is easy...

If encoding is not supported returns ERROR.

Note --- not exists total corect conversion to ASCII, this function try
convert chars those is _probably_ interpret-able in ASCII for
others use ' '. But for example for all Czech characters it is
sufficient ... hmm Chinese / JAP and other complicated langs have
bad luck here :-(

Re: to_ascii()

I had to back out the patch. It only compiles with multi-byte enabled.

Please submit a new patch.

Applied.

Re: to_ascii()

I see the following warnings in a gcc compile with -Wall:

ascii.c: In function `to_ascii_encname':
ascii.c:41: warning: control reaches end of non-void function
ascii.c: In function `to_ascii_enc':
ascii.c:47: warning: control reaches end of non-void function
ascii.c: In function `to_ascii_default':
ascii.c:53: warning: control reaches end of non-void function

Applied.

Grrr..... it's really bad day for me.

Please, ignore this warning now. I will work on to_char() and this
I resolve too. It's pedantic warning from a gcc, these functions
always end with elog(ERROR..) and not with some return. But a gcc
don't knows it :-(

(or you can add "return (Datum) NULL;" to these three lines if you don't
want wait for me next patch).

*Sorry* Bruce, I really didn't want kill your time....
