is_monospace

A monospace font is a font designed for text display where the the characters form a regular grid.

For Western languages this would mean that the advance width of all characters are the same, but this categorization also includes Asian fonts which include double-width characters: characters that occupy two grid cells. iswide returns a result that indicates whether a character is typically double-width in a monospace font.

The best way to find out the grid-cell size is to call [method@Pango.FontMetrics.get_approximate_digit_width], since the results of [ method@Pango.FontMetrics.get_approximate_char_width] may be affected by double-width characters.

Parameters:

this	a `PangoFontFamily`

Returns:

true if the family is monospace.
