Subject [jira] Commented: (LUCENE-1730) TrecContentSource should use a fixed encoding, rather than system dependent
Date Thu, 02 Jul 2009 18:15:47 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-1730?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12726596#action_12726596

Mark Miller commented on LUCENE-1730:
-------------------------------------

The trec data you are using is ISO-8859-1. Wouldn't it be conceivable that they might change
the encoding to UTF-8 at some point? Or that someone else has created trec compatible data
in another encoding? Or trec has data in different encodings? If something reads a source
of files, and the files could technically be in any encoding, I would expect things to be
configurable so that I can specify what encoding the files are in. It just seems like a good
standard feature with something that reads what are essentially pluggable files. The format
is going to be consistent, but why would the encoding necessarily be consistent?

> TrecContentSource opens InputStreamReader w/o a fixed encoding. On Windows, this means
CP1252 (at least on my machine) which is ok. However, when I opened it on a Linux machine
w/ a default of UTF-8, it failed to read the files. The patch changes it to use ISO-8859-1,
which seems to be the right one (and http://mg4j.dsi.unimi.it/man/manual/ch01s04.html mentions
this encoding in its example of a script which reads the data).
> Patch to follow shortly.
