I have some notes;

• it gives to me the infamous 'internal server error' that has response code 200. Not a 304.
• It seems to be the case for a number of characters, including any type of brackets except <>, colon (:) (but not semicolon), double quote (but not single quote), caret ^, tilda ~, forward slash.
• A number of characters have only a problem for search type directories, such as \ backward slash and + plus
• A number of characters have no problems, such as comma, period, semicolon, equals
• unicode does not seem to cause problems, such as 😁

Summary of found errors:

problems for any type: (){}[]:^~/"?
problems only for directory type: !+\-
