Subject: Pumping UTF-8 data mangles it
Download (untitled) / with headers
text/plain 679b
Attached is a self-contained test script that shows how pump does not manage to send all UTF-8 data to the child, despite the environment vars PERL_UNICODE=SDA LC_ALL=en_US.UTF-8 LANG=en_US.UTF-8 being set. I tried looking through IPC/Run.pm and by adding "use bytes;" to _write() that part will at least send the data correctly. However, I couldn't get it to read back the output from the child as UTF-8; it just reads the raw bytes interpreted as ISO-8859-1, and forcing all _read() strings to UTF-8 seemed like a really bad idea... Somewhere there must be a place where it does not respect the global binmode, since PERL_UNICODE=SDA should force all I/O to UTF-8 semantics.

I think IPC::Run should test the locale. If UTF-8 is used, call binmode(":utf8") on all pipe filehandles *before* using them. See perldoc -f binmode for more details.
