ION Script User's Guide: Creating ION Script Applications |

ION supports 8-bit ASCII character sets as defined by ISO 8859, including ISO 8859-1 (also called Latin-1). This character set consists of 256 characters. The first 128 characters make up the US ASCII character set, consisting of characters used in US English. The second 128 characters support languages used in Western European countries.
| Note For a table of ISO 8859 character sets, visit http://www.bbsinc.com/iso8859.html. |
In order to use 8-bit characters in an ION page using versions of ION prior to 1.2, it was necessary to insert either the character's Numerical Entity Reference or the Entity Name. The Numerical Entity Reference uses the format &#nnn;, where nnn is the decimal value of character. For example, the British pound symbol, ≤, can be inserted into an ION (or HTML) page using £. Some characters have been assigned an entity name to make it easier to remember the name for a character. For example, the British pound can be represented as £.
| Note Support for Entity Names is browser-dependent. |
In ION, all ISO 8859-1 characters can be natively inserted into ION pages, directly from the keyboard. (Note that ION still supports Numerical Entity References and Entity Names.)
