Bug 11374 – Wrong UTF-8 decoding when calling File.readln(buf) with typeof(buf) == string.

I'm sorry if this is not really a bug but just some ultra-obscure quirk. Anyway, doing something like: string buf; stdin.readln(buf); Appears to work, but seems to decode some characters wrong (consistently). Using "char[] buf;" or "stdin.readln()" both work. Here's a more complete test case: *************************************************************** import std.stdio; void main() { ubyte[] weirdcharacterbytes = [0xf0, 0x90, 0xa4, 0x80]; string weirdcharacter = cast(string)weirdcharacterbytes; { auto f = File("weirdcharacter.txt", "wb"); f.rawWrite(weirdcharacterbytes); } { auto f = File("weirdcharacter.txt", "r"); string s = f.readln(); writeln(s == weirdcharacter ? "PASS" : "FAIL"); } { auto f = File("weirdcharacter.txt", "r"); char[] s; f.readln(s); writeln(s == weirdcharacter ? "PASS" : "FAIL"); } { auto f = File("weirdcharacter.txt", "r"); string s; f.readln(s); writeln(s == weirdcharacter ? "PASS" : "FAIL"); } } *************************************************************** PASS PASS FAIL *************************************************************** Thanks.

Your example doesn't compile in the git-head. See bug 10517.

(In reply to comment #1) > Your example doesn't compile in the git-head. See bug 10517. Thank you, it appears that this bug has indeed been fixed. Also, this may sound like a rant or blaming someone else, and it very likely is, but the fact that the source link in the Phobos 2.063.2 documentation points to the prerelease version didn't help (obvious in hindsight, but no wonder I couldn't figure out which overload was being called and gave up). Also, I did indeed run a bugzilla search for 'readln', but the default filter doesn't display closed bugs, so I also couldn't find the closed bug you linked.
