Frament of torrent file with bug (binary data)

I use std.utf.validate to check validity string of UTF. And i catch
UTFException if string not valid. But... In debug mode i have AssertError:

core.exception.AssertError std.utf(950): Assertion failure

My code:

try {
    root.str = cast(string) store.str;   // from immutable(ubyte)[]
} catch(UTFException e) {
    root.str = toHexString!(LetterCase.upper)(store.str);

It work on release mode.
