Tried it. Shows Available.
Though I left a msg with my hosting provider and they sent me full settings of the server. There is such string there:
Registered Stream Filters
zlib.*, bzip2.*, convert.iconv.*, string.rot13, string.toupper, string.tolower, string.strip_tags, convert.*, consumed, dechunk, http.*, mcrypt.*, mdecrypt.*
convert.iconv – is what we need?
Thank you for your fast reply.
Looks like the server doesn’t use this function.
