Summary	0006111: When a client proposes an UID with a non-ascii character, SOGo takes it, but xml2wbxml failes on ActiveSync
Description	When a Client proposes an UID with a non-ascii character, like an accent circonflex in it, SOGo takes it, but unfortunately xml2wbxml then fails parsing the entry. That blocks the whole client from syncing ever again and I guess the only way to sanitize is to remove the affected entry and then resync the client calendar, which is a pain, unfortunately, that's why I classified it as severe error. See attachment for creation-messages and error response I suggest either to not use original uid for non-ascii characters or fix xml2wbxml to process such characters properly (if allowed by specification).
Steps To Reproduce	Make an invitation with "Fête blanche" in the subject and accept it on an IPhone conneted via EAS and let SOGO write it to the calendar. You will end up with an EAS <Sync> message like the attached one. Then try to sync the event with MS Outlook via EAS and you will end up with: "xml2wbxml failed: Parsing of XML Document Failed"
Tags	No tags attached.

Result in ActiveSync dispatcher:
--------------------------------
Apr 04 12:23:30 sogod [31551]: [ERROR] <0x0x558c6b1642e0[NSDataMalloc]> xml2wbxml failed: Parsing of XML Document Failed

I suggest either to not use original uid for non-ascii characters or fix xml2wbxml to process such characters properly (if allowed by specification).
