CentOS and Oracle linux are both rebuilds of RHEL - but NOT the same operating system
WHAT version of cent are you using ?
the ONLY supported versions are CentOS 5.9 and 6.4
-- soon to be 5.10 and 6.5
have a look at the cent base repo
yum search font
that will give you a list
and have a look at the language software groups
mind you you can only install software on a supported version of cent
yum install ??????
-------- or for a group ----------
yum groupinstall "Name of Group"
aslo ftp now uses BY DEFAULT binary and NOT ascii
so there is no need to convert something to use ftp
the FIRST post is about using text and ftp on a very OLD operating system
so for a modern OS
this is not needed
just use the DEFAULT ftp settings
