I have an API that among other things returns a URL for Google Static Maps, one of the URL parameters in that url is center. When outputing the beautified response to the html document the parameter ¢er= is turned into ¢er=.
Could you please be a little bit more specific, as I don't clearly understand the problem: e.g an example of the input you're giving to the beautifier (and which one? the jsbeautifier.org (in what browser?), or some of the command-line versions)?
Closing due to inactivity and missing information; comment please if you find the problem again, thank you!
