| | Languages and Character Sets |
 | | Computer systems vary greatly in the sets of characters they make available for use in electronic documents; this variety enables users with widely different needs to find computer systems suitable to their purposes, but it also complicates the interchange of documents among systems; hence the need for a chapter on this topic in these Guidelines. |
 | | The same character may be represented by many different glyphs; less obviously, the same glyph, may in certain circumstances correspond with different abstract characters, or be used with different interpretations, as when, for example, the Greek capital letter omega is also used to represent the unit of electrical resistance (ohm). |
 | | For local processing, on the other hand, use of characters from this area might prove convenient, since, if the corresponding font resources are available, users can see the characters more easily on their screens and analytical software might not be able to process entity references in the same way as characters. |
