Canonical name of the unicode is cp1047.

We have checked the supported encodings and this one appears not to be
supported.

Comments
EVALUATION Cp1047 support was added in 1.4.2 It should be listed in the 1.4.2 J2SE supported encoding list I will submit a separate bug to ensure that the docs are updated in 1.5 to reflect the support for this codepage/converter. ###@###.### 2003-09-23 The docs have been updated Cp1047 is supported in 1.4.2. However some commonly used aliases aside from "Cp1047" which *is* supported in 1.4.2 and notably "IBM-1047" are not provided as part of the lookup identifiers for this encoding. As part of the migration work for 4891216 (IBM codepage converter migration to use nio charset API) the required aliases have been included. I have modified the bug synopsis to request "IBM-1047" alias support for Cp1047. I will also downgrade the bug to p3 since Cp1047 has been supported since 1.4.2 albeit in a limited way. ###@###.### 2003-09-26 The IBM-1047 alias is now instituted as part of the migration of common IBM converters to use the java.nio.charset API/SPI (see bugID 4891216). This should be verifiable from b28 onwards of 1.5.0. Closing this bug out as duplicate of 4891216.
