This seems like the Cygwin command was launched from a non-Cygwin terminal or from a terminal where locale was not set to UNICODE. Please provide the results of "locale" command right before running your test binary. -- With best regards, Andrey Repin Sunday, October 4, 2020 14:16:17 Sorry for my terrible english... -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation: https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
