[BUG] Doesn't function properly when % is followed immediately by two or more numbers

[Jiawei1996]

Language Mode is C++

When the selected code within the string statement contains a % followed immediately by two or more number characters, codesnap will be unable to export images normally.

e.g. "%" is good, "%1" is good, "%11" is bad.

As mentioned in #140: The error occurs when there is at least one string of the form %00 - %ff, irrelevant of the casing, language mode or any other text adjacent to it.
