Calculate how much of a UCS-2 string will fit in a given width.
int TTF_MeasureUNICODE(TTF_Font *font, const Uint16 *text, int measure_width, int *extent, int *count);
|font||the font to query.|
|text||text to calculate, in UCS-2 encoding.|
|measure_width||maximum width, in pixels, available for the string.|
|count||on return, filled with number of characters that can be rendered.|
|extent||on return, filled with latest calculated width.|
Returns 0 if successful, -1 on error.
This reports the number of characters that can be rendered before reaching
This does not need to render the string to do this calculation.
Please note that this function is named "Unicode" but currently expects UCS-2 encoding (16 bits per codepoint). This does not give you access to large Unicode values, such as emoji glyphs. These codepoints are accessible through the UTF-8 version of this function.
This function is available since SDL_ttf 2.0.18.
