OSProcess reading utf8 files

Hi,

Reading an utf8 file with OSProcess results in some weird characters
showing up.

(PipeableOSProcess command: 'less /path/to/a/text/file') output.
-> inspect the bytestring and get some non-ascii characters fucked up.

Doing `less /path/to/a/text/file` in a terminal displays the file fine.

That's probably something stupid on my side but I cannot get it working.
Any idea ?

Cheers,

Francois

Francois,

The output of the PipeableOSProcess is based on a StandardFileStream
rather than a MultiByteFileStream, so it may not do what you expect
with a file containing non-ascii characters.

Note that the unix /usr/bin/less utility is intended for interactive
use with a terminal. You probably should use /usr/bin/cat instead.

HTH,
Dave

Hi Dave,

Ok! I'll try to get it work...

Yep 'less' was an example, I'm actually wrapping the exiftool perl library...
