IBM code page 874 (''CP874'', ''IBM-874'', ''x-IBM874''), also known as Code page 9066 (''IBM-9066''), differs from ISO/IEC 8859-11 in only nine symbols shown boxed in the following table:

Code page 1161

Code page 1161 (''CP1161'', ''IBM-1161''), is a variant of IBM code page 874. The only difference is the euro sign (€) in position DE_hex (222).
