Re: Convert HTML symbols to equivalent Unicodeby dorward (Curate)

Your question is very confusing.
Is "®" the result you get after parsing the HTML? i.e. the character and not an ampersand followed by an identifier and then a semi-colon? If so, then the parsing is working fine, and it is the output you need to worry about. (I mention this because PerlMonks takes HTML input, so you might have wanted to say ® rather then ®.)
Any XML library should be outputting something appropriate when given ® as input. Either it will output an entity (which should be absolutely fine, since you should be parsing XML only with an XML parser which can handle such things) or it will output the character in whatever character encoding is being used (so you just need to make sure you are outputting UTF-8 (or whichever unicode encoding you want) — how you do that depends on which XML library you are using.
Named HTML entities could screw things up in XML, but the decimal entity should not.
This doesn't make sense. XML is a data format. JSON is a completely different data format.
You can't parse anything in JSON.
You could store an XML document as a string inside a JSON object, but that shouldn't prevent you from using entities — you would parse the JSON to extract the string of XML, then put that string in an XML parser to extract the data from it.
What is the problem you are really trying to solve? You don't seem to have provided enough detail here.
