What is a random utf8 generator?
learn more about this toolWith this tool you can easily generate random multi-byte UTF8 text. You can choose how many random UTF8 strings to generate and their length. Additionally as UTF8 is multi-byte encoding, you can choose how many bytes to use per generated character. If you use one byte then you will simply generate random legacy data, but if you use two, three or four bytes, you'll get random UTF8 madness. Quick and powerful!
Random utf8 generator examples
Click to useRandom Two Byte UTF8 Sequences
In this example we generate eight random two byte UTF8 sequences, each of 16 characters in length. We only use UTF8 characters that are represented by two bytes.
