Text Replacer does not process \? properly

[SnowboundCabin]

Expected result: \? would match the literal character ? and thus adding a rule with regex \? and replacement ! would turn "Foo?" into "Foo!" Actual result: Message is still "Foo?"

Could not recreate the bug, as it seems to work correctly, as demonstrated here.
