Summary:	The plain text parser doesn't parse \ as a special character
Issue Type:	Bug
Affects Versions:	3.0 M3
Assignee:	Unassigned
Components:	Syntax - plain/1.0
Created:	10/Jun/25 12:10
Priority:	Major
Reporter:	Michael Hamann
Description:	Steps to reproduce: Parse some text containing \ with the plain text parser. Expected result: The \ character is parsed as special symbol and represented as such in the XDOM, similar to when the same text is parsed as xwiki/2.0 syntax for example. Actual result: The \ character is parsed as regular character and part of a word block in the XDOM.

	This was unintentionally fixed as part of ~~XRENDERING-790~~ as it wasn't clear to me that all \ in the regular expression were just escaping characters and none of them matched a plain \. As it is obvious from the definition of special characters and the XWiki syntax parsers that \ should be treated as a special character, I'm keeping the behavior change but making it more obvious with this issue. I've added an explicit integration test for all special characters to ensure that we properly test this behavior.
