Characters in User or Group DN's that will cause problems when using Crowd
As of Crowd 2.5.1, CWD-2042 - Getting issue details... STATUS is resolved. This document is now historical.
At present, the AbstractEncodingFilter used by Crowd, JIRA and Confluence silently translates certain 'dangerous' characters. The AbstractEncodingFilter exists because Microsoft Word uses some special Unicode characters for text (e.g. curly quotes). Not all fonts on non-Windows systems contain these characters. This causes issues in JIRA and Confluence when users copy and paste text from Word into a page or issue. Users on non-Windows systems will see question marks or other odd characters if their fonts don't have these characters.

Unfortunately, these translations obviously cause problems when querying for users or groups in Crowd which contain these characters.
