iOS Localization: Unicode character escape sequences, which have the form '\uxxxx' does not work

Question

We have key-value pair in Localization.string file.

\"spanish-key\" = \"Espa\\u00f1ol\";

When we fetch and assign to label then app display

Answer 1

NSString literals and strings-files use different escaping rules.

NSString literals use the same escape sequences as "normal" C-strings, in particular the "universal character names" defined in the C99 standard:

\unnnn      - the character whose four-digit short identifier is nnnn
\Unnnnnnnn  - the character whose eight-digit short identifier is nnnnnnnn

Example:

NSString *string = @"Espa\u00F1ol - \U0001F600"; // Español -                                                                     

                                                        
            

Answer 2

Just write the string in proper Unicode in Localization.string.

"spanish-key" = "Español";
