This file contains ambiguous Unicode characters that may be confused with others in your current locale. If your use case is intentional and legitimate, you can safely ignore this warning. Use the Escape button to highlight these characters.
# Tests of \C when Unicode support is available. Note that \C is not supported
# for DFA matching in UTF mode, so this test is not run with -dfa. The output
# of this test is different in 8-, 16-, and 32-bit modes. Some tests may match
# in some widths and not in others.
