ttfRenderUtf8Blended function
Render UTF-8 text at high quality to a new ARGB surface.
This function will allocate a new 32-bit, ARGB surface, using alpha blending to dither the font with the given color. This function returns the new surface, or NULL if there was an error.
This will not word-wrap the string; you'll get a surface with a single line of text, as long as the string requires. You can use TTF_RenderUTF8_Blended_Wrapped() instead if you need to wrap the output to multiple lines.
This will not wrap on newline characters.
You can render at other quality levels with TTF_RenderUTF8_Solid, TTF_RenderUTF8_Shaded, and TTF_RenderUTF8_LCD.
\param font the font to render with. \param text text to render, in UTF-8 encoding. \param fg the foreground color for the text. \returns a new 32-bit, ARGB surface, or NULL if there was an error.
\since This function is available since SDL_ttf 2.0.12.
