- # Script to dump a UTF-8 file as a list of numbered lines (mimicking GCC's
- # diagnostic output format), interleaved with lines per character showing
- # the Unicode codepoints, the UTF-8 encoding bytes, the name of the
- # character, and, where printable, the characters themselves.
- # The lines are printed in logical order, which may help the reader to grok
- # the relationship between visual and logical ordering in bi-di files.
