온라인 URL 디코더

My Python Flask App is unable to decode the devanagari text eg:"सिंगापूर" that I pass as urlparam from my postman. If I sen english text it handles it well.

My PostMan query :GET http://localhost:5000/getSimilarWord/सिंगापूर

from flask import Flaskfrom flask_restful import Resource, Apiclass DevnagriText(Resource):    def get(self, textInput):        print("parsed String is :",textInput)        return {'text': textInput} api.add_resource(DevnagriText, '/getWord/<string:textInput>')if __name__ == '__main__':    app.run(debug=True)

The output I get on console is

{    "text": "\u00818"}

Instead of

{    "text": "सिंगापूर"}

I need to run a query against a legacy table that stores URL encoded text. I need this text to be decoded in my results. How do I achieve this?

In Salesforce, I try to download a user profile pic. as we know the Profile pic stored as URL in a FullPhotoURl user field.I tried to covert that image URL into a Blob by using JavaScript but having CORS policy error:

Access to image at 'https://c.xyz.content.force.com/profilephoto/7294J000000bxaV/T' from origin 'https://c.xyz.visual.force.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Here is my JS code I tried:-

                  j$.ajax({                    headers:   {"Access-Control-Allow-Origin":"*", "Access-Control-Allow-Methods":"GET"},                    url : "https://c.um5.content.force.com/profilephoto/7294J000000bxaV/T",                    type : "POST",                    data : {},                    success : function(result){                        console.log('result',result);                    },                    error : function(jqXHR, textStatus, errorThrown) {                        alert('Error: '+jqXHR.status);                        alert('ErrorThrown: '+errorThrown)                    }                 });

What am I missing?

Is there any method that fully decodes a String ? For example I have

monta%25C3%25B1a , if I use UrlDecoder.decode method ONCE : it returns monta%C3%B1a and if I decodify AGAIN , it finally returns montaña (that is the fully decodified string).Is there any method or library in Java that achieves this result?

I am trying to read percentage encoded urls with umlauts, such as äüö,..., with Qt:

QString str = "Nu%CC%88rnberg"qDebug() << QUrl::fromPercentEncoding(str.toUtf8());

But the output is Nu¨rnberg instead of Nürnberg. How can I correctly decode urls with umlauts in this form?
