Short description of error
error message:
OpenColorIO Error: Error could not read 'F:\work*oS*\blender-2.77-windows64\2.77\datafiles\colormanagement\config.ocio' OCIO profile.
Color management: using fallback mode for management
A part of the BOLD notation is multi-byte character string.
Exact steps for others to reproduce the error
An error occurs at the time of start of blender in OpenColorIO when I install a 2.77 official release version in a file pass including the multi-byte character string.

@Sergey think you are our OCIO guy? unless @MartijnBerger wants to handle that windows mess… ;)

Fix wasn't really correct. Re-opening for further investigation. But it might be a limitation of OCIO API :S
istream can handle multi-byte character string, but is caused by the fact that multi-byte character string is included in a parameter to generate istream instance.
I think that you should preprocess the argument which is used to generate istream instance.
The basic cause thinks that type of the argument of Config::CreateFromFile is inappropriate.
It is nothing to do with
istream
. that part works just fine and config file is parsed just nicely. The issue appears when OCIO needs to access lookup table referenced in the config file. OCIO needs to know where to find those lookup tables and in normal case this is how it works:dirname
of that file name is used as a search path. So if lookup tables are referenced by a relative path in the config it all works just fine.Config::setSearchPath
(or something like that).The issue here is that both points (and underlying calls) operates with
char *
paths (and no _w* function extensions) which Windows API expects to be ANSI encoded a\, making it impossible to operate with multi-byte paths for OCIO.There might be some workarounds for that, that's where i am atm.

This is a limitation of 3rd party library API. I've reported it to the upstream: https://github.com/imageworks/OpenColorIO/issues/406
Will probably have time to look into solving it from OCIO side, but that's not a task of the bug tracker. So thanks for thee report, but closing it now.
