If libxml_use_internal_errors is set to `true` before parsing xliff file, the libxml errors are not cleared correctly. An error `Validation failed: no DTD found !` occurs in libxml errors after parsing and it's available outside the xliff parser (can break other functionality that use `libxml_get_errors` function).

[Finder][Urgent] Remove asterisk and question mark from folder name in test to prevent windows file system issues.

Bugfix: Yes
Fixed tickets: #11984 , #11985
Related tickets: #11970

Commit #11970 prevented Symphony from being checked out via windows due to invalid characters in a folder name within the tests.

The issue was reported in #11984  and was attempted to be fixed in #11985 but wasn't due to still including the question mark.

Please accept this ASAP as it entirely breaks any composer that relies on it.
