Leandro Reis created IO-471:
-------------------------------
Summary: Support for additional encodings needed in
ReversedLinesFileReader
Key: IO-471
URL: https://issues.apache.org/jira/browse/IO-471
Project: Commons IO
Issue Type: Improvement
Components: Utilities
Affects Versions: 2.4
Reporter: Leandro Reis
I¹m working on a product that uses Commons IO via Jackrabbit Oak. In the
process of testing the launch of such product on Japanese Windows 2012
Server R2, I came across the following exception:
"(java.io.UnsupportedEncodingException: Encoding windows-31j is not
supported yet (feel free to submit a patch))"
windows-31j is the IANA name for Windows code page 932 (Japanese), and
is returned by Charset.defaultCharset(), used in
org.apache.commons.io.input.ReversedLinesFileReader [0].
This issue can be resolved by adding a check for
'windows-31j' to ReversedLinesFileReader.
The attached patch includes such addition, as well as those needed to support
Chinese Simplified, Chinese Traditional and Korean.
A newline byte can never appear as part of a multi-byte character in any
of those encodings.
