series. However, it is defined as an alias of the close equivalent TIS-620 (which lacks the non-breaking space), and which can without problems be used for ISO/IEC 8859-11, since the no-break space has a code which was unallocated in TIS-620. Microsoft has assigned code page 28601 a.k.a. Windows-28601 to ISO-8859-11 in Windows. A draft had the Thai letters in different spots.

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:
