Robert Muir commented on LUCENE-3748:
-------------------------------------

I agree with the patch. We can easily add backwards compat here, no problem.

As far as any potential others, the only possibility from my perspective is U+FF07 FULLWIDTH APOSTROPHE, 
though I could go either way on that (since its a compatibility character)

Any other opinions?

> The current EnglishPossessiveFilter (used in EnglishAnalyzer) removes possessives using only the '\'' character (plus 's' or 'S'), but some common systems (German?) insert the Unicode "\u2019" (RIGHT SINGLE QUOTATION MARK) instead and this is not removed when processing UTF-8 text. I propose to change EnglishPossesiveFilter to support '\u2019' as an alternative to '\''.
