Using a UTF8 Decoder in Cross-browser Testing
A UTF8 decoder can be useful if you're doing cross-browser testing. For example, if you're writing form processing browser tests, then often you need to validate and make sure the data in the input form contains only valid characters (such as email address or a website address). With this utility, you can generate various test cases for Unicode and ASCII form data in UTF8 encoding. Also, you can use this program to verify the given UTF8 has been correctly encoded. UTF8 allows only specific byte sequences and if the bytes have errors, then you'll see them output here. Another use case is debugging UTF8-encoded data. As you decode it, you'll see if the input data decodes correctly and produces the results you expect.
