why does argv remove some of my characters?

fixed the issue. Will look into that further That's because in cmd, ^^ is an escape sequence for ^. So if you enter ^^ it will only send one ^ to your program, as explained here.
You can see this if you put echo ^^ into the command line, which will print ^.

like below fixes the issue it's not a matter of python, you need to escape it in the calling shell. simply escape quotes as \" and semicolons as \;.
code :
$ python testme.py "With these words she greeted Prince Vasili Kuragin, a man of high rank and importance, who was the first to arrive at her reception. Anna Pavlovna had had a cough for some days. She was, as she said, suffering\" from la grippe; grippe being then a new word in St. Petersburg\""

How do i check argv[1] doesn't have any alphabetical characters?

With these it helps Despite the title, it sounds like you really want to do is check whether every single character in the input argument is a digit. You can achieve this by iterating over it, checking that every element is a digit using std::isdigit.
Here's a sketch using the std::all_of algorithm:
code :
size_t len = strlen(argv[1]);
bool ok = std::all_of(argv[1], argv[1] + len,
                      [](unsigned char c) { return std::isdigit(c); } );

Ruby: ARGV breaks accented characters

hope this fix your issue For some reason, Windows doesn't use UTF-8 in your console. So, although Ruby expects UTF-8 encoded string, it gets Windows-1252 encoded string.
So you have several possibilities (which I can't test as I, fortunately, don't use Windows):

**argv contain a lot of characters than expected

help you fix your problem You need to NUL terminate your C-style strings, and that includes allocating enough memory to hold the NUL.
Your array is a byte short (must be char command[strlen(argv[1])+4+1]; to leave space for NUL), and you should probably just use something like sprintf to fill it in, e.g.:
code :
 sprintf(command, "vim %s", argv[1]);`

Can you pass non-ascii characters to argv?

To fix the issue you can do Back in the MS-DOS days you could have entered 0xF9 = 11111001 = 249 with the key combination ALT-249 typed on the keypad.
For Windows this still works like explained in this article.
