This appendix should tell you everything you need to know about the fonts in the X distribution. Not every font may be supported by particular server vendors, and some vendors may supplement the set. Also, a more descriptive naming scheme has been proposed, but it has not been accepted as part of the X standard at this writing.
Table J-1 lists the fonts provided in the standard X distribution. Fixed-width and variable-width fonts are listed in separated columns. Table J-2 describes the maximum metrics for characters in the font. This should help you choose a font and decide how much space to allow for strings using the font. Finally, all or most of the characters in each font are shown actual size, as they would appear on a 900 × 1180 pixel, 10″ × 13.5″ screen (Sun). On a screen with different pixel density, these fonts would appear a different size.
Table J-2 describes the maximum metrics for each font. These are the values of the max_bounds member of XFontStruct (which is an XCharStruct structure with the members shown in the table). Note that it is unlikely that any single character will be the biggest in all the measurements simultaneously; these describe the largest lbearing of any character in the font, the largest rbearing for any character in the font, and so on. For a description of each of the character measurements, see Volume One, Section 6.2.3.
The remaining pages of this appendix show the characters in each font, actual size, as they would appear on a 900 × 1180 pixel, 10″ × 13.5″ screen (Sun). On a screen with different pixel density, these fonts would appear a proportionally different size.
For most fonts, the entire character set is shown. For very large fonts, we have sometimes shown just a few characters to save space. Also, fonts that begin with many blank characters are shown with most leading blanks removed. Therefore, you can't always get the character number of each cell in the font by counting from the first cell we have shown. Use xfd to quickly determine the code for a particular cell.
