A free online tool to decode utf8 characters by using this tool
If you're executing cross-browser testing, a UTF8 decoder may be helpful. For example, you generally need to check and ensure that the data in the input form contains only valid characters while developing form processing browser tests (such as email address or a website address). You may create a variety of test cases using this tool for Unicode and ASCII form data in UTF8 encoding. This application also allows you to check the accuracy of the specified UTF8's encoding. Only particular byte sequences are permitted by UTF8, and faults in those bytes will be displayed here. The debugging of UTF8-encoded data is another use case. You may check to verify if the input data decodes successfully and yields the outcomes you anticipate as you decode it.
