Support for Py3.x

Does supporting Python >= 2.7 mean that I can run this tool for Py3.6?
This is purely py2 --> py3 encoding problem.

$ stackcollapse-hprof mymem.hprof > output-folded.txt

Traceback (most recent call last):

Yes, it should. Travis CI is configured to run the test suite with Python 3.2 .. 3.5.

This is purely py2 --> py3 encoding problem.

I assumed that hprof ASCII output was... ASCII. However, it is not. It seems to be... UTF-8 encoded. (I played LC_ALL and LANG and always got an UTF-8 encoded file but I am not fully confident that the file will always be UTF-8 encoded).

I will push a fix tomorrow.

However, I am a bit puzzled by position 87. 87 should be in the header part which is pure ASCII. Would you mind sharing your hprof file?

Sorry, I can't upload this snapshot - it's 500 Mb and I don't know what sensitive information could be there. I created it with Pycharm --> Tools --> Create Memory Snapshot, you can try to do it yourself. It's a tool for addressing Pycharm memory issues, so it's probably not meant to be used with third party packages like yours.
