[jira] [Commented] (TIKA-897) UTF-8 encoded XML is detected as text/plain because of UTF-8 BOM

    [ https://issues.apache.org/jira/browse/TIKA-897?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13258241#comment-13258241 ] 

Nick Burch commented on TIKA-897:
---------------------------------

We had support for detecting XML files that are ASCII, UTF-8 no-BOM, UTF-16LE and UTF-16BE.

In r1328370 I've added detection + unit test for UTF-8 with a BOM

We don't detect XML in UTF-32 (with or without BOMs), but I'm not sure if that's worth adding or not?

> Detection of XML fails when encoded as UTF-8. The UTF-8 BOM: 0xEF,0xBB,0xBF causes the XML detector to fail when trying to match "<?xml" at the beginning of the input stream.
