Save the code into a .sc file in your Extensions/ directory, recompile, and then:\r\n\r\n\"%E5%A4%A7%E5%AE%B6%E5%A5%BD\".decodeHex;\r\n-> 大家好\r\n\r\nThis probably works only for UTF-8. SC can save the individual bytes of Unicode characters into String objects, and the IDE will print UTF-8 code points correctly, but there is no way to switch the IDE to other Unicode variants.",
