CABuddy – Unicode CAB Compressor – Release 9/7/2018
Edit: Newer version available here.
I looked for 2 hours for Unicode CAB compressors and found nothing. What I did find was someone who wrote a Unicode-supported library for CAB files on CodeProject. I got my hands on it and fixed some minor bugs and compilation issues. Made a GUI, and walla, a modern x64 CAB compressor.
This is just the initial release. I have bigger plans for it (notice that I left status bar in by accident), but for now I wanted to put something out there.
