Unicode support in filesystem breaking compatibility?
Posted: Mon Sep 26, 2016 7:21 pm
Hi. It seems in recent releases of KolibriOS (I tested this for the Sept 26 2016 release currently put up at http://builds.kolibrios.org/eng/latest-distr.7z), getting current folder for thread (SF 30.2) does not work as expected (there may be other functions whose behavior might have changed, but I have only tested 30.2). For example, the following code snippet -
should ideally store "/RD/1" (2F 52 44 2F 31 as it does in older versions) into the buffer. However with the new release it prefixes "2F 03" to the result (2F 03 2F 52 44 2F 31). Can someone verify this behavior? @dunkaist suggests this might be due to the unicode support introduced in filesystem.
