I just downloaded Creative Suite CS6 Master Collection trial some days ago and I loved it, so I activated.

For handling text I'd go to try the InDesign forum, where various aspects of "language" have been discussed. There are ways to change the interface language, but that's a very different issue from applying the correct spelling dictionary or hyphenation rules to a piece of text: English-language ID, for example, comes with dictionaries for many other languages, which can be invoked via the language attribute.
Edit: Almost forgot a very useful node over on Typophile for users of CS6.
