This came up in rust-lang/rust#106098 (comment).

The 2 possible behaviors that seem reasonable to me are either:

keep the non-breaking space characters as is; or
replace non-breaking space (U+00A0) with ordinary space (U+0020) inside of comments.

The current behavior is not a way that I would expect rustfmt to behave.

Repro:

$ echo -e '/*\n  normal spaces\n\u00a0\u00a0non-breaking\u00a0spaces\n*/' | rustfmt
/*
  normal spaces
non-breaking spaces
*/
