I will take this bug, thanks.
Comment 2 Regina Henschel 2012-08-02 13:38:57 UTC 
I think, that a browser is not suitable to examine, whether AOO uses the clipboard correctly. The character set and the font of a displayed website depends on the settings of the browser and the settings in the website.
Comment 3 Chen Peng 2012-08-07 07:59:06 UTC 
1. Root Cause:
  In Firefox or Chrome, if the unicode is equal or larger than 0xd800 and smaller equal or than 0xdbff, and the next unicode is equal or larger then 0xdc00 and equal or smaller than 0xdfff, using such two 16-bit unicode can't display the data such as the last 5 charaters of line 8 in the sample. 
2. Resolution:
Need to convert such two 16-bit unicode to a 32-bit unicode to show the content.

Comment 5 Chen Peng 2012-08-07 08:16:22 UTC 
It is correct if paste such content in IE or MS. The content of last 5 characters in clipboard is using two 16-bit unicode format, but paste such content in Chrome, Firefox or Safari, it is wrong, need to change the two 16-bit unicode to a 32-bit unicode to show the right content.
