Answer 1

Basically, you might have compiled a file which is encoded in another charset that is not the default charset of your operating system. One way is to delete those characters that can not decoded by your default encoding, but I prefer the other way which is just using Notepad++ to trans-coding your file. To achieve this goal, click Encoding->Convert To xxx, where xxx is your operating system default encoding.
