Title: Need help with '∞' symbol
Post by: Scipi on December 01, 2011, 04:39:28 am

Hello,

I am trying to display the infinity symbol for a game I am making.

The code I use to get it is:

Code: [Select]


AmmoText = sf::String(sf::Unicode::Text(L"\u221E"), sf::Font::GetDefaultFont(), 10.f);


But nothing shows up for it.

How can I make it so that '∞' will be outputted?

Thanks

The font that you use must contain this symbol. The default font is Arial, loaded with the Latin-1 characters set. So it does not have the infinity symbol.

Ok, I see. What font can I use that includes the symbol?

Maybe Arial includes it, but the SFML default font doesn't load it.

So first you must load your own font, passing it a characters set that contains your symbol. Once it works, you can find a font which works with that. Maybe Arial does it, it has a lot of Unicode symbols. You can check with the "characters table" if you're under Windows.

I checked and Arial does seem to include it. However it's still not showing up.

Here's the code I have now:

Code: [Select]


    sf::Font Font;
    sf::Uint32 CharSet[] = {0x221E,0x0};
    Font.LoadFromFile("arial.ttf", 30, CharSet);

...

    AmmoText = sf::String(sf::Unicode::Text(L"\u221E"), Font, 10.f);

Sorry for the double post, but when I use the code above I get this message in the console:

Code: [Select]


     Failed to load font "arial.ttf" (Cannot open Resource"


It only occurs when I pass the character set to the font.

How do I fix this? Thanks :D

So maybe it doesn't have this symbol.
