Description

See this code:

https://github.com/uutils/coreutils/blob/30fd234e59ab76e81a8277c7d2f139942fd3a0d0/src/uu/df/src/table.rs#L265-L271

It gets the width of the lossy string but stores the raw bytes. I think this at least deserves a comment explaining this is intentional. Because it's not entirely clear to me if doing a lossy conversion may use more or less cells.

Research direction

Start in src/uu/df/src/table.rs at lines 265-271 and inspect how the lossy string width and raw bytes are used together. Confirm whether the behavior is intentional, then document that relationship with a comment and verify the df-related tests still pass.
