Steven Rowe commented on LUCENE-2167:
-------------------------------------

bq. This version uses Character.toUpperCase() [non-locale-aware] and also only iterates over tld.charAt() [what was the reason for the strange substring stuff?].

I looked for Character.toUpperCase(), didn't find it (no idea why), so went with the strange substring stuff to use the String version instead ...

I plan on integrating your patch with mine, to make a single one, including a definition for a StandardTokenizer replacement.  I have implemented URL, Email and Host rules, just gotta write some tests now.

> It would be really nice for StandardTokenizer to adhere straight to the standard as much as we can with jflex. Then its name would actually make sense.
> Such a transition would involve renaming the old StandardTokenizer to EuropeanTokenizer, as its javadoc claims:
> bq. This should be a good tokenizer for most European-language documents
> The new StandardTokenizer could then say
> bq. This should be a good tokenizer for most languages.
> All the english/euro-centric stuff like the acronym/company/apostrophe stuff can stay with that EuropeanTokenizer, and it could be used by the european analyzers.
