questions about ScanUnsupportedChars.ps1(Is it able to stop the script execution in the middle; Can the script be ran multiple times using a batch file)

My customer wants to use below script to checking whether there is any unsupported characters in the file name.
https://github.com/Azure-Samples/azure-files-samples/blob/master/ScanUnsupportedChars/ScanUnsupportedChars.ps1

He has below questions. I did some labs, found that seems it is not possible to stop the script execution process in the middle by either pressing Ctrl+Z, Pause Bread key, ESC key and so on. Could you give any guidance please ? Thank you.

1, How to stop ScanUnsupportedChars in the middle of the execution process and what are the concerns when stopping it?
2, Is it possible to run ScanUnsupportedChars multiple times using a batch file?
3, In the DESCRIPTION of ScanUnsupportedChars.ps1, it says ' a file name is supported but this script might say its not supported', will this cause the supported file name be renamed to a different name ? What is the impact if the supported file name is recognized as un-supportted file name ?
Or are there any examples or documents about what kind of supported file name might be recognized as unsupported file names ?

***
Note - this script might report false positive i.e. a file name is supported but this script might say its not supported.
This is by design to keep the script simple and allow customer to rename such files proactively.

Read ScanUnsupportedChars/ScanUnsupportedChars.ps1 and its DESCRIPTION first. Trace how the script handles interruption, repeated invocation from a batch file, and reported false positives, then document answers and the impact of each case for the three questions raised.
