扩展ASCII

Question

当我尝试保存在Eclipse中的.java文件与扩展ASCII字符，例如█返回以下错误

Save could not be completed. Try File >Save as if the problem persists 
Reason: 
Some characters cannot be mapped using "Cp1252" character encoding. 
Either change the encoding or remove the characters which are not 
supported by the "Cp1252" character encoding. 

而且我在该对话框中选择将文件保存为UTF-8。如果我这样做，eclipse会继续编译正确吗？或者有可能我会介绍错误？

Answer 1

使用unicode，不扩展ascii。

http://en.wikipedia.org/wiki/List_of_Unicode_characters#Block_elements列出了ASCiiesque块字符。
