sdl ttf Windows-1250编码

Question

In file text.txt I have this sentenc:

"Příliš žluťoučký kůň úpěl ďábelské ódy."

(I think Windows uses Windows-1250 code page to represent this text.)

In my program I save it to a buffer

char string[1000]

and render string with ttf to SDL_Surface *surface

surface = TTF_RenderText_Blended(font, string, color);
/*(font is true type and support this text)*/

But it gives me not correct result:

I need some reputation points to post images so I can only describe that ř,í,š,ž,ť,ů,ň,ď are not displayed correctly.

Is it possible to use ttf for rendering this sentence correctly?

(I tried also TTF_RenderUTF8_Blended, TTF_RenderUNICODE_Solid... with worse result.)

Answer 1

The docs for TTF_RenderText_Blended say that it takes a Latin-1 string (Windows-1252) - this will be why it isn't working.

You'll need to convert your input text to UTF-8 and use RenderUTF8, or to UTF-16 and use RenderUNICODE to ensure it is interpreted correctly.

How you do this depends on what platform your app is targeted to - if it is Windows, then the easiest way would be to use the MultiByteToWideChar Win32 API to convert it to UTF-16 and then use the TTF_RenderUNICODE_Blended to draw it.

Answer 2

My solution will be this:

Three input files. In first file there will be a set of symbols from czech alphabet. Second file will be sprite bitmap file where graphic symbols will be sorted in the same order as in first file. In my program symbols from third input file will be compared with symbols from first file and right section of sprite will be copied on sreen one by one.

I will leave out sdl_ttf. It has some advantages and disadvantages but I think it will work for my purposes.

Thanks for all responses
