add en_US.UTF8 support

[Wesley M.A.]

Hi,

I run OpenBSD 5.3-current i386 (xbase.tgz included)
I install php-5.3 /gd /zip
added owncloud 5.0 from owncloud.org
I read the faq : 10.20.1 - Configuring the active character set

I tried this : export LC_CTYPE="en_US.ISO8859-1"
and restart apache same error in Owncloud :
setting locale to en_US.UTF-8/en_US.UTF8 failed. Support is probably 
not installed on your system

Any idea ?

Regards,

Wesley M.A
