World's simplest browser-based UTF8 encoding error checker. Just import your UTF8 data in the editor on the left and this tool will instantly validate its encoding. Free, quick, and very powerful. Import UTF8 – validate UTF8. Created by geeks from team Browserling.
With this tool you can easily find all errors in UTF8-encoded text. Valid UTF8 has a specific binary format. If it's a single byte UTF8 character, then it is always of form '0xxxxxxx', where 'x' is any binary digit. If it's a two byte UTF8 character, then it's always of form '110xxxxx10xxxxxx'. Similarly for three and four byte UTF8 characters it starts with '1110xxxx' and '11110xxx' followed by '10xxxxxx' one less times as there are bytes. This tool will locate mistakes in the encoding and tell you where they occured.
This example shows a red badge because the input UTF8 has an encoding error at byte 59. Byte 59 indicates that there should be a two byte sequence following it but only one byte follows. This is malformed UTF8.
This example shows a green badge because the input UTF8 is valid.
You can pass input to this tool via ?input query argument and it will automatically compute output. Here's how to type it in your browser's address bar. Click to try!
