I know of several totally different ways to solve that kind of problem:
I. As used by the "matchparen" plugin: examine the character under the
cursor, maybe some more around that, and behave differently depending on
what is found.
II. Most versatile but limited to a given filetype: examine the syntax
groups under the cursor by means of the functions
syinID()
synIDattr()
synIDtrans()
(qq.v.)
III. As used by the matchit plugin: I don't know how it does it (you may
go and look), but matchit doesn't match { with } if one of them is
inside a comment and the other not.
Best regards,
Tony.
