The functionality of utPLSQL is dependent on the session parameter NLS_SORT

Describe the bug

If some alphabetic sorting rules of a language other than English are used, depending on the name of the schema being tested, the framework may break and throw, for example, the following error message:
[Error] Execution (5: 1): ORA-20202: Invalid path format: test.*
ORA-06512: at "UT3.UT_RUNNER", line 158
ORA-06512: at "UT3.UT_SUITE_MANAGER", line 36
...

The cause of the error is explained in this old stackoverflow article:

Expected behavior
I would expect this framework to work on any Oracle database, regardless of Oracle settings.
