The "Basic Graphics Programming" tutorial for XCB includes a section on fonts and text (http://www.x.org/releases/X11R7.5/doc/libxcb/tutorial/index.html#font). Unfortunately, this part of the tutorial uses server-side, core fonts whose use is discouraged. This section of the tutorial should be removed, replaced with an Xft section, or at least annotated with a warning that Xft provides better font and text support than the old core fonts system. For example, the "Fonts in X11" documentation (http://www.x.org/releases/X11R7.5/doc/fonts/fonts.html) says, "While X.Org will continue to maintain the core fonts system, toolkit authors are encouraged to switch to Xft as soon as possible."
