Assigning an incompatible type to a variable of a different type is a type error. Changing `binary_contents` back to `contents` produces a type error like this on that line:
`clang/cindex.py:3332: error: Incompatible types in assignment (expression has type "bytes", variable has type "str | TextIOWrapper")`
Good point with the repetition though, I'll make separate PRs for these to collect this into a common function.
