SCIM and other Input Method Editors; which one to use?

Hi, Guys.
I've just switched my desktop to Mageia, after a troubled experience with another Linux distro. Still struggling to set everything as it used to be, but I'm confident it will be a successful change.
However, I have some odd requirements: I need language support for non-latin writing systems (namely, Japanese, and Arabic) in my computer, so I can keep on using and learning them more!
I've been using SCIM (Smart Common Input Method) to write Japanese and Arabic. But a friend of mine ("guilty for my Linux addiction and recent Mageia adoption!"
) told me that SCIM would be no longer supported, and so I should choose another IME? Is that true? if so, which one would you suggest?
Thanks in advance!
