https://issues.dlang.org/show_bug.cgi?id=12877 Issue ID: 12877 Summary: std.random.uniform cannot handle dchar variates Product: D Version: D2 Hardware: x86_64 OS: Linux Status: NEW Severity: enhancement Priority: P1 Component: Phobos Assignee: nobody puremagic.com Reporter: joseph.wakeling webdrake.net The uniform!T specialization, which returns a random variate covering the entire bit range of an integral or character type T, will fail in the event that T == dchar because dchar.max is significantly less than the largest number that can be stored in dchar's 32 bits. This in turn leads uniform!"[]"(dchar.min, dchar.max) to fail, because the integral/character-type uniform() calls uniform!ReturnType in the event of a closed interval with bounds [ReturnType.min, ReturnType.max].
