Copying and Pasting Chinese Input to GB18030 Web Forms

∟Copying and Pasting Chinese Input to GB18030 Web Forms

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

In this test, I wanted to see if IE allows me to copy and past Chinese characters from UTF-8 and Big5 Web pages to GB18030 encoded Web forms.

1. Ran IE with this URL: http://localhost/Web-Form-Input-Chinese-GB18030.php, and remove the default text from the input box.

2. Ran another IE window with this URL: http://localhost/Web-Form-Input-Chinese-Big5.php. Copy and paste the Chinese characters from this page to the input box of the GB18030 page. The Chinese characters shows up in the input box correctly.

3. Entered a forward slash (/) in the input box of the GB18030 page.

4. Ran another IE window with this URL: http://localhost/Web-Form-Input-Chinese-UTF8.php. Copied and pasted the Chinese characters from this page to the input box of the GB18030 page. The Chinese characters showed up in the input box correctly.

6. Clicked the Submit button on the GB18030 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 GB18030 Pages

The returning page URL also confirmed that Chinese characters were copied and pasted correctly. Notice that GB18030 contains traditional Chinese characters. One of traditional characters has a special encoding: 0x9943, corresponding to %99C:

http://localhost/Web-Form-Input-Chinese-GB18030.php
  ?Input=%EB%8A%D2%95%99C%2F%B5%E7%CA%D3%BB%FA%2F%EB%8A%D2%95%99C
  &Submit=Submit

As a reference, here is the Chinese text in Hex numbers received by the PHP script:

EB8AD29599432FB5E7CAD3BBFA2FEB8AD2959943

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