These are the converters and Charsets supported by IBM Java 2 version 1.4. JDK 1.4 introduces a new set of character conversion APIs as part of the nio. The names for the nio Charsets are normally the IANA primary name.
Most of the converters are also supported in earlier releases. The notes indicate whether this is an IBM only converter, and the release in which it was introduced. Some of the converters were introduced in service refreshes. This document reflects the current state of these releases.
The nio Charset name can be used as an alias for legacy converters, and the legacy converter name can be used as an alias for nio Charsets. Other available aliases are shown in the aliases column. The alias names are case independent. Some aliases have been added in releases after the one in which the converter was added.
The images of the codepages show the glyphs and unicode mappings of the converter. However, the unicode values may not exactly match the ones used by Java. Only the first part of complex codepages are shown.
