    Description

      RFC7950 states that:

       A "length" statement restricts the number of Unicode characters in
 the string.

      This is distinct diffrent what java.lang.String.length() provides:

      Returns the length of this string. The length is equal to the number of Unicode code units in the string.

      with the following (from java.lang.Character):

      In the Java SE API documentation, Unicode code point is used for character values in the range between U+0000 and U+10FFFF,
and Unicode code unit is used for 16-bit char values that are code units of the UTF-16 encoding.

      We should not be checking the String.length(), but rather String.codePointCount(). Audit all enforcement points for correct checks.
