I installed and started using your pastebin last week, and today we noticed that some legitimate content (example bellow) was removed. I looked in the code and think it's due to remove_invisible_characters removing HTML special charaters pasted in hexadecimal (I think).
Is this a feature? Could it be something wrong in my configuration? Is there a work arround?
Example (C code):
// When pasted, only "s" remains as the format string.printf("%12s", "I am a string");
I am sorry if it is not the right place for this. Thank you in advance.
