Copying and Pasting Chinese Input to UTF-8 Web Forms

This section provides a test on copying and pasting Chinese input text from GB18030 and Big5 Web pages to UTF-8 encoded Web forms.

After tried Web form with Chinese input text with 4 different encodings: UTF-8, GB18030, and Big5, I wanted to try to copy and paste Chinese text from one Web page window to another Web page window with a different encoding.

I did the following to copy and pasted Chinese text from GB18030 and Big5 Web pages to a Web form with UTF-8 encoding:

1. Ran IE with this URL: http://localhost/Web-Form-Input-Chinese-UTF8.php, and removed the default text from the input box.

2. Ran another IE window with this URL: http://localhost/Web-Form-Input-Chinese-GB18030.php. Copy and paste the Chinese characters from this page to the input box of the UTF-8 page. The Chinese characters shows up in the input box correctly.

3. Entered a forward slash (/) in the input box of the UTF-8 page.

4. Ran another IE window with this URL: http://localhost/Web-Form-Input-Chinese-Big5.php. Copied and pasted the Chinese characters from this page to the input box of the UTF-8 page. The Chinese characters showed up in the input box correctly.

6. Clicked the Submit button on the UTF-8 page. The pasted characters were received and returned back to the returning Web page. The returned Chinese characters showed up correctly.
Copying and Pasting Chinese Characters to UTF-8 Pages

The returning page URL also confirmed that Chinese characters were copied and pasted correctly:

http://localhost/Web-Form-Input-Chinese-UTF8.php
  ?Input=%E7%94%B5%E8%A7%86%E6%9C%BA%2F%E9%9B%BB%E8%A6%96%E6%A9%9F
  &Submit=Submit

This test shows that IE is smart, it automatically converts the pasted Chinese characters from GB18030 and Big5 encoding to UTF-8 encoding in a Web page form encoded as UTF-8.
