import std.regexp; void main() { ubyte[] data = [0xFF]; RegExp re = new RegExp(`.*`); re.test(cast(char[])data); } --- Caused me some headache when I to process some non-Unicode files and forgot to convert the data.

std.regexp is designed to work only with valid UTF strings. To validate UTF strings, which should be done for input coming from an untrusted source, use the function std.utf.validate().
