Entering Latin1 Characters with Alt Keycodes

This section describes how to enter Latin1 characters with Alt keycodes on an English keyboard.

In the previous example, the default Latin1 characters in the input text box were pre-generated by the PHP script using Latin1 code values.

If you are using a European key board, you can easily enter some text in European languages to test my Latin1 test PHP Web page form.

But if you are using an English key board, it is not easy to enter any special characters used in some European languages. One way to Latin1 characters on a Windows system is to use Alt key codes in the following key sequence:

<Alt>+0nnn
   <Alt>+ means pressing and holding down the Alt key.
   0nnn means pressing 0 and one, two or three numeric keys
      on the numeric key pad.
   Release the Alt key after numeric keys.

To use numeric keys on the numeric key pad, the "num lock" must be turned on by pressing the "num lock" key.

The numeric keys pressed present the decimal value of any Latin1 character code. The leading 0 is important. If you skip the leading 0, you Windows will take the Alt key codes as Windows 1252 encoding.

The table below shows you Latin1 special characters with code values between 0x80 and 0xFF:
