String operation issues with special sign (+) in a compare operator

[b-jesch]

Bug report

Describe the bug

String operations fails if an operator contains a plus sign (+).

For some reasons I need to compare the videoresolution string from an info label "Player.Progress(eoft_gamut)" wich is available on Amlogic devices. This Label returns strings like "HDR10 ...", HDR10+ ...", "HLG .." and so on. A comparison with the String Operations String.StartsWith(), String.Contains() etc. fails on "HDR10+". Other comparsion with operators without "+" sign is fine.

Expected Behavior

A comparsion with special chars using String functions should work as expected.

Special chars like "+" needs a special treatment
