I get something that's bit-for-bit the same as what's in unaccent.rules. So there's clearly a platform difference between here and there.
I'm using Python 2.6.6, which is what ships with RHEL6; have not tried it on anything newer.
Well, that's embarrassing. When I looked I couldn't see anything that looked platform specific. I'm on Python 2.7.6, which shipped with Mint 17. We use other versions of 2.7 on our production platforms. I'll take another look, and check the URLs I am using.
The problem is that I downloaded the latest version of the Latin-ASCII transliteration file (r34 rather than the r28 specified in the URL). Over 3 years ago (in r29, of course) they changed the file format (https://unicode.org/cldr/trac/ticket/5873) so that parse_cldr_latin_ascii_transliterator loads an empty rules set. I'd be happy to either a) support both formats, or b), support just the newest and update the URL. Option b) is cleaner, and I can't imagine why anyone would want to use an older rule set (then again, struggling with Unicode always makes my head hurt; I am not an expert on it). Thoughts?
