How to change it to preg_replace?

You can use your existing Regex almost unchanged in a preg_replace(). Just add delimiters and a case-insensitive modifier. You get
preg_replace('#[0-9]+\.+[0-9]#i','',$cart['unit']);
In fact, the case-sensitivity is irrelevant since your pattern only matches 0-9 and .

NSArray from NSCharacterSet

When I'm trying
print(NSCharacterSet.URLQueryAllowedCharacterSet())
it prints
<__NSCFCharacterSet: 0x1759b900>
How do I make it more informative?
You can get a representation of the character set using bitmapRepresentation which could be queried. Or you could do basically the same thing with a loop over all characters and using characterIsMember:. The output is potentially big...
There isn't really a simple option or a generic concise output to what you're asking for. It isn't a common requirement.
