octave: libinterp/corefcn/oct-stream.cc annotate

annotate libinterp/corefcn/oct-stream.cc @ 26705:c13143821eef

Add front-end support for encodings in "fopen" (bug #55452). * file-io.cc (Ffopen): Add support for input and output argument "encoding". (do_stream_open): Check if encoding is valid. * oct-stream.cc (stream_list::get_info): Return encoding. * io.tst (fopen): Adapt for new syntax. Add test for writing and reading with specified encoding.
