DESCRIPTION
The function is similar to except that it uses 2-byte or 16-bit characters. Both functions also use both the foreground and background pixels of the GC in the destination.
The effect is first to fill a destination rectangle with the background pixel defined in the GC and then to paint the text with the foreground pixel. The upper-left corner of the filled rectangle is at:
[x, y - font-ascent]
The width is:
overall-width
The height is:
font-ascent + font-descent
The overall-width, font-ascent, and font-descent are as would be returned by using gc and string. The function and fill-style defined in the GC are ignored for these functions. The effective function is and the effective fill-style is
For fonts defined with 2-byte matrix indexing and used with each byte is used as a byte2 with a byte1 of zero.
Both functions use these GC components: plane-mask, foreground, background, font, subwindow-mode, clip-x-origin, clip-y-origin, and clip-mask.
and can generate and errors.
DIAGNOSTICS
- A value for a Drawable argument does not name a defined Window or Pixmap.
 - A value for a GContext argument does not name a defined GContext.
 - An window is used as a Drawable.
 - Some argument or pair of arguments has the correct type and range but fails to match in some other way required by the request.
