Occasionally, we see requests from folks who want to publish a blog in non English languages, and don't trust the Google Translator, or translated blogs using a Translator Gadget.
Every different world language has its own peculiarities - character set, font, grammatical constructions, even direction of type will differ from language to language. To support these peculiarities, Blogger has a language selection, for each language which they support. This roughly parallels the ongoing development of the Google Translator.
Use the Language selector for your blog, at Settings - "Language and formatting", and look at the Language pull-down list.
When you publish a non English blog, find and select the language of your interest, before you publish posts. This may present a challenge, to those who want to produce a blog in more than one language, simultaneously. Any blog can have one and only one language selection.
If you want to publish in, say, English and French, you'll need two blogs - an English blog and a French blog, each in the right language selection. To publish in English, French and German, you'll need three blogs - an English blog, a French blog, and a German blog, each in the right language selection.
Having setup an cluster or set of blogs, combine and merge them into a cohesive set, so it all looks like one blog, to your readers. And use "hreflang" to aggregate the cluster, to the search engines.
If I want to publish The Real Blogger Status in English, French, and German, I could have "de-blogging-nitecruzr.blogspot.com", "en-blogging-nitecruzr.blogspot.com", and "fr-blogging-nitecruzr.blogspot.com", each blog with its proper language selection. Since I publish in my own domain, "Nitecruzr.Net", I would have "de.blogging.nitecruzr.net", "en.blogging.nitecruzr.net", and "fr.blogging.nitecruzr.net".
I use the ISO 2 character Language Codes for all my multi-lingual blog names.
