LL| |// Check that column numbers are denoted in bytes, so that they don't cause
LL| |// `llvm-cov` to fail or emit malformed output.
LL| |//
LL| |// Note that when `llvm-cov` prints ^ arrows on a subsequent line, it simply
LL| |// inserts one space character for each "column", with no understanding of
LL| |// Unicode or character widths. So those arrows will tend to be misaligned
LL| |// for non-ASCII source code, regardless of whether column numbers are code
LL| |// points or bytes.
