Subject [jira] [Updated] (TIKA-683) RTF Parser issues with non european characters
Date Wed, 17 Aug 2011 12:30:50 GMT

     [ https://issues.apache.org/jira/browse/TIKA-683?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Michael McCandless updated TIKA-683:
------------------------------------

    Attachment: TIKA-683-unicode-testcase.patch

I was curious/nervous whether the RTFParser (and RTF format itself) properly handled non-BMP
unicode characters, so with Robert Muir's help I created a basic test case (attached) and
indeed at least for these Gothic characters in particular non-BMP is handled fine: the test
passes.

It turns out (apparently) each \uXXX is a UTF16 code unit, not a unicode code point.
