Could you provide a little more detail? What's the input compared with the output? Also, which platform? Android and/or iOS?

I'm talkink about iOS. For example assume that I have this values in strings.xml: <string name="addLabelSimple">"Hello /n Friend"</string> If I try to print it in a Label, with: text:L("addLabelSimple"), in 2.1.4 I'l get correctly two lines. The first with the word "Hello" and the second with the word "Friend" But in 3.0.0 RC2, I get only this: "Hello /n Friend". So the backslash en is ignored as a special character and it is printed as a normal character sequence.

Thanks. Tested and confirmed on iOS 6 - in 2.1.4 GA it works fine, in 3.0 GA the \n is printed as a normal string.

@Daniel, is that acceptable printing \n as a normal string?
Daniel Sefton 2012-12-11

Natively the special characters are taken into account: https://developer.apple.com/library/mac/documentation/Cocoa/Conceptual/LoadingResources/Strings/Strings.html#//apple_ref/doc/uid/10000051i-CH6-SW13 And it's a regression, so it would break existing apps which use those characters. But it's up to you if you think it's worth fixing over other issues I guess.

I'm reviewing the old python code, and I don't think we should escape the backslashes. We didn't do so previously.
