One point for vocabs.... I thought we had decided that all controlled vocabularies would be defined in the standard as English, and that it was up to the local implementation to provide translations in other languages.
If this is still the case, does this also apply to open vocabs? If this is the case then I'd go option #3 (fallback #2). Otherwise if we are still going English only then option #1 seems logical.

This is exactly why I support 3... If we support 2, we need to define either a limited character set (e.g. latin-1 only) with well defined rules, or a well defined rules on case sensitivity for ALL unicode characters, and be willing to break other languages like Turkish...
The header on:
http://www.unicode.org/Public/UCD/latest/ucd/CaseFolding.txt
Helps... Also points out that some case transitions involve going from one code point to two...
Hmm... I did find W3C's case folding page:
https://www.w3.org/International/wiki/Case_folding
So, anyone who has an opinion on this topic should read it, and then decide if they want to change their vote...
More info on case mapping from Unicode:
http://unicode.org/faq/casemap_charprop.html
Another fun example from the Unicode page: "For example, while the default uppercase mapping of "a" is "A" and the default mapping of "à" is "À", the uppercase conversion of " e vais à Paris" in some forms of French might be "JE VAIS A PARIS" Notice how the "à" is uppercased as "A" in this case."
IMO, the spec should be 3, but we provide non-normative text on how organizations and vendor products should allow such input.. If all the tools follow the rules, then the issues about comparision is a non-issue...
