This file contains ambiguous Unicode characters

This file contains Unicode characters that might be confused with other characters. If you think that this is intentional, you can safely ignore this warning. Use the Escape button to reveal them.

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