Compress - Decompress not equal

[mrjasan]

I have been using the lib for a long time. Nothing but praise.

However, this happens:
LZString.CompressToBase64("1-1072")
// "IwWmAYHYCYA="

LZString.DecompressFromBase64("IwWmAYHYCYA=")
// null

I tried to debug the process and I couldn't find out what could be wrong.

I won't be able to test that right away, can you check if https://github.com/pieroxy/lz-string behaves in the same way?

I tried the same string with the JS lib and it does work as expected.

Damn. To be completely honest, I don't master the compression algorithm itself. My best idea would be to follow both algorithm and figure out where they start to differ. That's a painful process, and one that I won't be able to do in the very short term; if you're in a rush, that's what I would suggest that you do first.

If you want to reduce the area of failure, you can try the UTF16 Compress/Decompress version for that very string, if it works, that would mean the problem is in the base 64 decoding itself.

When I have time, I'll see if I can spend some time looking into this. Sorry I can't provide faster help.
