is7bit -- determine if byte array contains only 7-bit bytes.

Determine if the byte data contains any 8bit bytes (i.e. bytes with the most significant bit set).

Download Chilkat Ruby Library

require 'chilkat'


data_bytes = [ 0x01, 0xFF, 65, 66, 67, 0xC0, 0xC1, 0xC2, 0x61, 0x62, 0x63 ]
data = Chilkat::CkByteData.new()
data.append(data_bytes.pack("C11"), 11)

if (data.is7bit() == true)
    print "All bytes are between 0 and 0x7F inclusive!" + "\n";
else
    print "Some bytes are 8bit!" + "\n";
end
