Anyone know where I can find Khmer, Malayalam, and other foreign fonts (and IPA characters)?

It kinda bugs me that Macs are so unequipped with foreign fonts. I know most people don’t give a rat’s ass about foreign fonts and foreign characters, but I do and it pisses me off that Windows comes pre-equipped with all kinds of foreign fonts and Mac is severely lacking. I can’t seem to find any Khmer or Malayalam fonts online that will work. Does anyone know where I can find these fonts so I can display Khmer and Malayalam text on my computer?

Additionally, does anyone know where I can get IPA characters? I need them for linguistics and I would like to embed them in Microsoft Word documents.
