ucar.unidata.util.ISO646

public final class ISO646
extends Object

Byte Classification as ISO 646 ranges, in the manner of \invalid input: '<'ctype.h\> in the C locale.

The motivation for this class is that the character classifications are it is intentionally restricted. isupper(c) is only true for 'A-Z'. It is important to only use this where it is appropriate, where the input is declared to be ISO 646. We use it for decoding meteorological bulletins.
