i18n code does not work from threads on some plaforms, so it is disabled in Blender when called from non-main thread. Means that we have to go to a slightly different approach, with dirty tag and generating string on request for UI. Note: Also had to update the `info` string size, to fit with expensive asiatic scripts in utf-8... Using mem for that kind of runtime data is not really nice, but for now it will have to do.
