Fails If Title Name Has Characters that Can't Be Used in Filename

[YisroelTech]

When downloading a book with a title that has characters that aren't allowed in a filename (and not specifying a new title with -title) the process fails:

Can it be added to the script to sanitize the title to delete/replace all characters not allowed in a filename?

The characters (at least on Windows) include:

/ (forward slash)
< (less than)
> (greater than)
: (colon - sometimes works, but is actually NTFS Alternate Data Streams)
" (double quote)
/ (forward slash)
\ (backslash)
| (vertical bar or pipe)
? (question mark)
* (asterisk)

I actually notice now that the getBookTitle function seems to already be doing that for the \. Can the rest be added?

Lines 29 to 43 in 8a10cf7

	func getBookTitle(configjs string) (string, error) {
	r := regexp.MustCompile(`("?(bookConfig.)?bookTitle"?[=]"(.*?)")|"title":"(.*?)"`)
	match := r.FindString(configjs)
	if strings.Contains(match, "=") {
	match = strings.Split(match, "=")[1]
	} else if strings.Contains(match, ":") {
	match = strings.Split(match, ":")[1]
	} else {
	return "", errors.New("could not find book title")
	}
	match = strings.ReplaceAll(match, "\"", "")
	return match, nil
	}
