Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Add basic backend for encodings in file streams (bug #55452). * oct-stream.h (base_stream): Store encoding in class. * oct-stream.cc (do_scanf_conv): Convert strings from encoding. (do_printf_string): Convert strings to encoding. (base_stream::printf): Convert format string to encoding. * oct-stdstrm.h (octave_stdiostream, octave_tstdiostream, octave_zstdiostream, create): Pass encoding through to base_stream. * oct-prcstrm.[cc,h] (octave_iprocstream, octave_oprocstream, create): Pass encoding through to octave_stdiostream. * oct-strstrm.[cc,h] (octave_istrstream, octave_ostrstream, create): Pass encoding through to base_stream.
