I use emacs so that meant practically every prefix character would annoy me at some point. I ended up using C-\ since that almost never gets used by anything (I was surprised it could even be detected by terminals).

C-\ is one of my favorite Emacs keybindings :). You use it to change input methods, in my case to write e.g. Greek letters and other Unicode symbols in plaintext files using TeX notation.

I sometimes like to program using Unicode variable names when doing physics/math, and this is an easy way to do so built into Emacs.
