Fancy f# method names with `` `` are escaping according to some rules, and to make managed name full compatible we need to fully unescape. #4969 fixes the most painful problem that prevents discovering completely. But in ideal case the CIL name should be fully unescaped so it can be found through reflection.

I have run a few manual tests and here are the characters that gets transformed (not exhaustive list):

• \ escaped as \\
• ' escaped as \'
• " escaped as \"
• @ escaped as @5

I will look at more cases now.
