Operators, arrows, dashes, units in documentation
Describe the bug
A selection of false positives in doc comments:
15 | Convert `usize` → `u32`

Expected behavior
Characters like arrows and m-dashes should be supported.
Operators like =, ~ and % should be supported outside of code blocks.
Use of units like 0.35mm should be supported outside of code blocks.

I am very happy to support these, but it's difficult to strike a balance of character sets to allow and those to deny, it's oftentimes project specific. Depend strongly on external input. Technically these are fixable with regex exceptions, but I think there is a common set of i.e. SI suffixes that would be well suited to get their separate opt-out config value with default on.
In terms of characters, I would advocate that the following should be allowed:
- Everything under the "Arrows" blocks, including supplements (see https://www.unicode.org/charts/)
- Everything under the "Mathematical Operators" blocks
- Maybe also "Geometric Shapes"? Not sure about this.
Regarding suffixes, I don't think there's a clear-cut answer. One can peruse International System of Units but there are many ways of combining SI prefixes with units, only some of them being commonly used.
Then there are a few suffixes you won't find under SI units, for example 16px or 2em (both used for font sizing).
