If you have written an application that is using the Intent output plugin to receive the scan data, the character will be passed to your app as is. If you are using the keystroke plugin, embedded non printable characters can cause issues like this.
You could set up an Advanced Data Formatting Rule in your profile to get around this.
The simplest in your case could be a rule with no criteria, just 2 actions
Action 1 Replace String: Find String \x1d Replace String $$$$ (or whatever you want to see in your application).
Action 2 Send Remaining.
With the above rule, you would see 6360$$$$4K when you scan your barcode. You could use any combination of printable characters (or just one character) in place of the $$$$.
