says:

From https://docs.oracle.com/javase%2F9%2Fdocs%2Fapi%2F%2F/java/lang/Float.html#valueOf-java.lang.String-,
https://docs.oracle.com/javase/specs/jls/se8/html/jls-3.html#jls-3.10.2,
and https://docs.oracle.com/javase/specs/jls/se8/html/jls-3.html#jls-Digits,
fullwidth Unicode digits are not applicable. Moved to JDK as an
enhancement.
