NumericField doesn't valid properly numbers > 1000 with locale fr-Fr

Module version(s) affected

5.1.x

Description

Because the length of the strength is checked, the numeric values with a narrow non breakable spaces as produced by the NumberFormatter class will fail to valid properly

How to reproduce

set locale to fr_FR
input a number >= 1000
without space, it works
it's the formatted on display with a narrow non breakable spaces
if you try to save again, it fails

Possible Solution

don't check the strlen as a way to validate parsing works
replace narrow non breakable spaces by regular spaces
