# Project website: https://github.com/cztomczak/cefpython

# In Python 2 all cefpython strings are byte strings, but in Python 3

# all cefpython strings are unicode. Unicode issues were discussed

# in Issue #60: https://github.com/cztomczak/cefpython/issues/60

# Unicode issues were discussed on cython-users, see posts by Stefan

# Behnel: https://groups.google.com/d/topic/cython-users/VICzhVn-zPw/discussion

# See the "basestring" comment in cefpython.pyx.

# Note that bytes != str != unicode != basestring in Cython

# Any bytes/unicode encoding and decoding in cefpython should

# be performed only using functions from this file - let's

# keep it in one place for future fixes - see Issue 60 ("Strings

# should be unicode by default, if bytes is required make it

# explicit").
