TT_OS2.y_subscript_x_offset

Specifies a font designer’s recommended horizontal offset for subscript characters. It is from the character origin of the font to the character origin of the subscript’s character. If a font does not include all of the required subscript characters for an application, and the application can substitute characters, this parameter specifies the recommended horizontal position from the character escapement point of the last character before the first subscript character. For upright characters, this value is usually zero; however, if the characters of a font have an incline (italic characters) the reference point for subscript characters is usually adjusted to compensate for the angle of incline.
