For such cases I find the Python style most appropriate. It says that you use some consistent default (e.g. always single quote), but for all a strings that require escaping, you should use the delimiter with the least (preferably no) escaping.

Note that this is easier in Python than JavaScript because Python provides more string delimiters:

    'He said hello.'

    'He said "hello".'

    "Don't say hello.'

    '''Don't say "hello".'''

    r'Some regex\sstuff'
