Testing Latin1 Alt Keycodes with IE
This section provides a test on Latin1 Alt keycodes with Internet Explorer (IE).
To test on entering Latin1 characters as Alt keycodes, I used the same PHP script, Web-Form-Input-Latin1.php, described in the previous section.
1. Start Internet Explorer (IE) with this URL: http://localhost/Web-Form-Input-Latin1.php.
2. Press the "num lock" key to turn on "num lock" for the numeric key pad.
3. In the text input box, remove the default text. Now enter <Alt>+0128 by pressing and holding down the Alt key and pressing 0, 1, 2, 8 on the numeric key pad. Release the Alt key. The Euro sign shows up.
4. Repeat the same process to enter four more Alt keycodes: <Alt>+0169, <Alt>+0231, <Alt>+0232, and <Alt>+0233.
5. Click the Submit button. The five Latin1 characters shows up on the returning Web page with their Hex number values confirming that the PHP script received them correctly.
6. Check the page URL in the page address box. The five Latin1 characters are encoded inside the URL:
http://localhost/Web-Form-Input-Latin1.php ?Input=%80%A9%E7%E8%E9%EA&Submit=Submit
Conclusion:
- IE default encoding is Latin1, if "charset" is not provided in the HTML header.
- Latin1 characters can be entered into Web forms displayed on IE.
- Latin1 characters can be received by PHP scripts through the $_REQUEST array.
