Hello, Codeforces!

I have been facing a problem since last 1-2 months. Whenever I copy a solution by clicking "Copy" from a submission page and then submit the same solution (or after some edit), I am getting Compilation Error.

The compilation message is like

Can't compile file:
program.cpp:3:1: error: stray '\302' in program
Â
^


Example, I copied this 59853141 submission which verdict is Wrong Answer.

After submitting this code, the submission 59853172 is getting Compilation Error.

I hope, the Codeforces authority will take care about that issue.

UPD: The bug is fixed now.

 » 5 months ago, # | ← Rev. 2 →   +11 Yes ; something needs to be done to fix the copy button...However ; I have noticed that if I manually point my cursor to the starting point of the code and then scroll it till the end ( Select all code manually using mouse ) ; and then copy-paste it ; the issue vanishes...!Although keeping in mind that this is a little time consuming process ( As compared to pressing copy button ) ; it solves the problem !( However I still feel that something must be done with the copy button as that is a lengthy process... )
