Hi!
I just begin learning smarty,when I rewrite an application with
smarty, I encounter a strange problem .the following simple
statement,seems doesn't work:

$somestr = iconv("UTF-8","GB2312",$somestr);

when I move to another application directory,It works. so I think it
just doesn't work in an smarty application directory.
but why?how can I use iconv in smarty?
besides,mb_convert_encoding doesn't work either.

any is highly appricated!
