when the custom language changes, the title command is mirrored

Steps to reproduce the bug:

1. create a custom language (resources pack)
2. use a title with a sequence of special characters (paste this command for example:/title @a actionbar {"text":"\u2b24\u2b24\u2b21"})

Observed results:

certain characters are mirrored (only those that use the code ex: u2b24, not this: ¶)

Expected results:

fonts should behave normally (even if you only change part of the language and not the whole language. see textures for example)
