Entering special characters in Windows programs

Common ASCII codes

In Windows programs the individual characters of the ASCII character set can be inserted into your text by holding down the Alt key and typing a number on the number pad.They don’t work with the numbers along the top of your keyboard.

Make sure NumLock is on.

Here are the ones I find most useful:

Commonly used ASCII symbols from the standard set

174 « 175 » 0252 ü
156 £ 0162 ¢ 0165 ¥
0248 ø 158 × 0169 ©
172 ¼ 171 ½ 0190 ¾
0150 0151 0133
167 º 0178 ² 0179 ³

You may have different requirements, check the full set of 200-odd more characters from Alt+32 — Alt+0255 is on this Just Wondering page along with a broader explanation.

This table shows the less commonly known ones which use Alt+Numpad 1 — Alt+Numpad 31.

These are not to be confused with the much more extensive HTML character codes for inserting characters into web pages. See them on this Just Wondering page.
