From site,

https://www.mercurial-scm.org/wiki/ SupportedPythonVersions Python_3.x_support Python 3.x has no relation to Windows Unicode filename support, see EncodingStrategy. Mercurial is actively being ported to Python 3. As of Mercurial 4.3, some commands work on Python 3. However, Python 3 is not yet a supported platform. Mercurial will never support Python 3.0 to 3.4 because of missing support for the % operator on bytestrings (bytes in Python 3). Fixable with a script change with no user intervention, perl -pi -e 's|(^#!/usr/bin/python)$|${1}2|g' $( which hg ) hg --version Mercurial Distributed SCM (version 4.8) or, with, alias hg='/usr/bin/python2 /usr/bin/hg' -- You are receiving this mail because: You are on the CC list for the bug.
