Notes

* The Underline text may appear blue on some PC terminals. This is a holdover from the early days of the IBM PC, where the underline attribute on the text-only screen appeared in blue text on the color screen.

* The A_ALTCHARSET line may look different on your terminal, depending on the character set available.

* The A_INVIS attribute line may not appear at all.
