Entering Extended Characters with Alt-Num

DOS and Windows allow you to create Extended Characters such as y-umlaut with the help of a numeric code. To enter any character from the IBM PC Extended Character (ECS), which is standard on DOS, hold down the Alt key while you enter the 3-digit decimal code. For example, Alt-152 is y-umlaut in ECS. Since HP uses the Roman-8 Character Set, the Reflection Terminal Emulator for DOS accepts Alt-152, but translates the character into decimal 239 (what HP expects for the Roman-8 y-umlaut character).

The situation in MS Windows is more complex and the only way to simplify it is to get a National Keyboard. To be compatible with DOS, you can still use Alt plus a 3-digit ECS code, but only if the character exists in the ANSI Character Set used by Windows. Windows then converts the character from the ECS code to the equivalent ANSI code. For example, y-umlaut is entered as Alt-152 but is translated to decimal 255. Or you can enter the ANSI code, but must convert it to 4-digits by preceding it with a 0 (zero). Thus Alt-0255 is also y-umlaut. Reflection for Windows accepts either the 3-digit ECS code or the 4-digit ANSI code, but translates either into the Roman-8 equivalent. Reflection translates both Alt-152 and Alt-0255 into decimal 239.

Warning: be sure to use the Numeric Keypad when keying in an Alt-Number and remember to engage the Num Lock key.

To find the 4-digit Windows code for a character, use the Character Map applet of the Accessories drawer. Select some font, such as Arial, click on the character you want, then note the 4-digit code displayed at the bottom of the window.
