Python regex to convert non-ascii characters in a string to closest ascii equivalents.

Question

I'm seeking simple Python function that takes a string and returns a similar one but with all non-ascii characters converted to their closest ascii equivalent. For example, diacritics and whatnot should be dropped. I'm imagining there must be a pretty canonical way to do this and there are plenty of related stackoverflow questions but I'm not finding a simple answer so it seemed worth a separate question.

Example input/output:

"Étienne" -> "Etienne"

Doing a search for 'iconv TRANSLIT python' I found: http://www.tablix.org/~avian/blog/archives/2009/01/unicode_transliteration_in_python/ which looks like it might be what you need. The comments have some other ideas which use the standard library instead.

There's also http://web.archive.org/web/20070807224749/http://techxplorer.com/2006/07/18/converting-unicode-to-ascii-using-python/ which uses NFKD to get the base characters where possible.
