-------------------------------------

related to this issue, Steven has added support for unicode text segmentation 
properties to the 1.5 dev branch of jflex: 
http://sourceforge.net/mailarchive/message.php?msg_name=4A747D60.4090904%40odyssey.net

we should be able to start prototyping a different definition of ALPHANUM, etc 
that solves this issue (and improves tokenization of many languages!)

>                 Key: LUCENE-1702
>                 URL: https://issues.apache.org/jira/browse/LUCENE-1702
>             Project: Lucene - Java
>          Issue Type: Bug
>          Components: contrib/analyzers
>            Reporter: Robert Muir
>            Priority: Minor
>
> While adding tests for offsets & type to ThaiAnalyzer, i discovered it does 
> not type Thai numeric digits correctly.
> ThaiAnalyzer uses StandardTokenizer, and this is really an issue with the 
> grammar, which adds the entire [:Thai:] block to ALPHANUM.
> i propose that alphanum be described a little bit differently in the grammar.
> Instead, [:letter:] should be allowed to have diacritics/signs/combining 
> marks attached to it.
> this would allow the [:thai:] hack to be completely removed, would allow 
> StandardTokenizer to parse complex writing systems such as Indian languages, 
> and would fix LUCENE-1545.
