Amazon Marketplace Web Service (Amazon MWS) uses character encoding based on ISO 8859-1. This
section will clarify just how you should format and use character encoding in Amazon MWS.
ISO/IEC 8859-1:1998, Information technology — 8-bit single-byte coded graphic
character sets — Part 1: Latin alphabet No. 1, is part of the ISO/IEC 8859 series of
ASCII-based standard character encodings. It is generally intended for Western European
languages. It is the basis for the most popular 8-bit character sets, including
Windows-1252 and the first block of characters in
Unicode. The HTML 2.0 standard defined its document character set as
ISO 8859-1. HTML5 has changed this to Unicode character encoding (ISO/IEC 10646,
Information technology — Universal Coded Character Set (UCS)). Since the first block
of unicode characters is essentially the same as ISO 8859-1, compatability is
Prior to the introduction of Unicode, ISO/IEC 8859-1 was used as the basis of other
encodings and has several aliases. For example, iso-ir-100,
csISOLatin1, latin1, l1,
IBM819, CP819, and others. The safe practice is to
conform to ISO 8859-1 when using Amazon MWS.
