[Feature Request] Extend AUTO_TRA with the ability to replace single characters

[ALIENQuake]

With the context of #227, can you add the ability for AUTO_TRA to be able to replace certain Unicode characters from the list (global or local) before loading replacement for @tra from subdir. The requirement would be so that source .tra files are using UTF8 encoding.

Example:

û > u
„ > "
” > "
… > ...

This would reduce or even eliminate the requirement of additional tra files for larger mods only for replacing a few characters, to match a "classic" style.

I don't like this. It's really wading into wrong waters.

I'm not saying yes or no yet. I figured I'd try to hack something together before replying, but it's dragging on, so I guess I'll get back to you, maybe?
