problem with unicode. [modified]

Peter_in_2780

Because that's the way \u_nnnn_ works. Big brother to the \x_nn_ convention for single byte characters. Borrowing a couple of sentences from the Java Language Specification, section 3.2: A Unicode escape of the form \u_xxxx_, where xxxx is a hexadecimal value, represents the Unicode character whose encoding is xxxx. This translation step allows any program to be expressed using only ASCII characters.

\u_nnnn_ doesn't work any particular way, it's just a string.. Of course it works that way in Java and C# and no doubt some other places as well, but there's no guarantee that it always does and OP should have specified it

Well, this is the C# forum... :doh:

Why does that matter? It's not about the string "\Uanything" (ie a string containing the actual character), but about a string containing "\\Uanything" that has to be converted the the first form. Anything could still be in any form - nowhere did he say that it originates from C# sourcecode.

I didn't have a problem understanding what OP wanted to do. Luc didn't have a problem. Richard didn't have a problem. jschell didn't have a problem. OP didn't have a problem understanding Luc's answers. I'm not going on a troll-feeding expedition. End of discussion.

And let me remind you, you are wrong. The OP did not specify that the number had to be in HEX, therefore it was not clear.

David1987

Actually they all had problems understanding what he meant. Luc's first answer doesn't answer the question, Richard's answer doesn't the question, Luc's first version of his second answer parsed it as decimal aswell IIRC and jschell just noted a problem with what the OP is trying to do.

Fuck you. It was a legitimate discussion. You are the troll here, not me.

Precisely, because I did not think the question was clear, and it had already received enough suggestions from other people. BTW I was not confused about the hex/decimal question; as you rightly pointed out the OP did not specify what the number format was.

Wrong. I edited to improve the error checking, basically I added s==null || s.Length!=6 || s[0]!='\\' || s[1]!='U' to the if(...) throw statement. Now stop this silly dispute, none of us know exactly what the OP intended, as is often the case, unfortunately. That is why I ended up providing two different answers, assuming one of them would hit the actual question. :)
