Bug 11068 – raw formatting of chars and strings is wrong

//---- foreach(C ; TypeTuple!(char, wchar, dchar)) { auto app = appender!string(); formattedWrite(app, "[%r] [%r]", cast(C)'a', to!(const(C)[])("aa")); writefln("[%(%x, %)]", app.data().representation()); } //---- //What I expected [5b, 61, 5d, 20, 5b, 61, 61, 5d] [5b, 61, 0, 5d, 20, 5b, 61, 0, 61, 0, 5d] [5b, 61, 0, 0, 0, 5d, 20, 5b, 61, 0, 0, 0, 61, 0, 0, 0, 5d] //What I got [5b, 61, 0, 0, 0, 5d, 20, 5b, 61, 61, 5d] [5b, 61, 0, 0, 0, 5d, 20, 5b, 61, 61, 5d] [5b, 61, 5d, 20, 5b, 61, 61, 5d] //---- foreach(C ; TypeTuple!(char, wchar, dchar)) { auto app = appender!string(); formattedWrite(app, "%r", to!(const(C)[])("日本語")); writefln("[%(%x, %)]", app.data().representation()); } //---- //What I expected [e6, 97, a5, e6, 9c, ac, e8, aa, 9e] //9 UTF code units [e5, 65, 2c, 67, 9e, 8a] //3 2-Byte code units [e5, 65, 0, 0, 2c, 67, 0, 0, 9e, 8a, 0, 0] //3 4 byte code units //What I got.
