Title: Encoding problem, Xcode
Post by: poq on September 26, 2012, 02:09:40 pm

Hi,

Just found this promising library and then stumbled with an encoding problem.

I use Xcode 4.2 and SFML 2 RC (installer). Source files are encoded in UTF-8.

I am trying to get Cyrillic chars to be shown properly using the SFML Application template:

    // Create a graphical text to display
    sf::Font font;
    if (!font.loadFromFile(resourcePath() + "mplus-1p-medium.ttf"))
        return EXIT_FAILURE;
    sf::Text text(L"\u043A к k", font, 50);
    text.setColor(sf::Color::Black);

(there's a Cyrillic K instead of html code in the source, seems there's a problem with encoding on the forums too  :D).

Default font which comes in Resources doesn't have non-Latin characters, so I've tried some other unicode-compitable fonts. And tried to follow similar issues posted on the forum but without much luck.

So, unicode sequence works, but the same Cyrillic letter typed as usual doesn't:

Is there a way to solve this in my case?

It seems that your compiler doesn't interpret the input file as UTF-8: your Cyrillic 'k' in UTF-8 is encoded as 0xD0 0xBA, but we can see that the printed characters are the 0xD0 and 0xBA characters of the Latin-1 character set (might be another one, a lot of character sets are compatible with Latin-1). So the compiler interprets your 2-byte UTF-8 character as two seperate 1-byte characters.

Thanks.

So far two options solved it for me when rendering text:

1. Changing compiler from Apple LLVM to LLVM GCC in project properties.
2. Or converting strings from utf-8 to wide (while still using Apple LLVM). I have not figured how Utf::toWide works yet though, but it showed typed characters correctly.

Neither of them will help with title encoding.

Or maybe you should just play with the corresponding compiler flags (which I don't know, but I know that they exist).

So how do you convert them?

Nothing helps with title encoding, it's not supported yet ;)

Works perfectly on Windows  :). I've tried it on Windows 7 with VS 2010, and both title and sf::Text worked correctly from scratch.

Just this way:

sf::Utf<8>::toWide(str.begin(), str.end(), str1.begin());

Also, seems to be relevant to the issue:
