Single Quotes in Marker Popups Break HTML

See original GitHub issue

map_1 = folium.Map(location=[-23.5505, -46.6333],
                   zoom_start=12)

folium.Marker([-23.550519999999999, -46.633308999999997], popup = 'name').add_to(map_1)
folium.Marker([-23.5505, -46.6333], popup = "name'with'quotes").add_to(map_1)

map_1.save('marker_name_test.html')

Problem description

If a marker popup string contains single quotes, HTML parsing in web browsers breaks and the output HTML file can’t be rendered.

Expected Output

A correctly rendered HTML page with the single quotes properly escaped or stripped from the popup string.

Output of `folium.version`

‘0.5.0’

Thanks for the comment @MCOfficer. Thankfully this issue has been fixed as far as I know in #962, which will be in the next release.

seeing this error pop up over and over again on SO, i’d recommend at least printing a warning if the html contains an unescaped single quote.
