    • Method Detail

      • toPrintableLatin1

        static java.lang.String toPrintableLatin1​(java.lang.String s)
        Converts its parameter to another String which contains only printable Latin-1 characters but not leading, trailing, or consecutive spaces.
        Parameters:
        s - the String to convert.
        Returns:
        a printable Latin-1 String sans superfluous spaces.
