Query the metrics (dimensions) of a font's 16-bit glyph.
int TTF_GlyphMetrics(TTF_Font *font, Uint16 ch,
int *minx, int *maxx,
int *miny, int *maxy, int *advance);| font | the font to query. |
| ch | the character code to check. |

Note that this version of the function takes a 16-bit character code, which covers the Basic Multilingual Plane, but is insufficient to cover the entire set of possible Unicode values, including emoji glyphs. You should use TTF_GlyphMetrics32() instead, which offers the same functionality but takes a 32-bit codepoint instead.
The only reason to use this function is that it was available since the beginning of time, more or less.
This function is available since SDL_ttf 2.0.12.
