问题
I frequently edit Python code using IDLE and occasionally when I perform a Save I receive an I/O Warning.
I am assuming that I have inadvertently added a Non-ASCII character, and I do not really want to declare the cp1252 encoding.
Is there an easy way to find and delete the Non-ASCII that the Warning relates to?
The OS Version involved is Windows 7, and the Python version is 2.6.5
回答1:
The regex [^ -~] will match anything except printing ASCII characters. It should be able to find your stray non-ASCII character.
Use it with IDLE's Search dialogue (Ctrl + F, or Edit → Find); it can search by regex:
