[jira] [Commented] (ARROW-16000) [C++][Dataset] Support Latin-1 encoding

    [ https://issues.apache.org/jira/browse/ARROW-16000?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17510462#comment-17510462 ] 

David Li commented on ARROW-16000:
----------------------------------

AFAIK, support for encodings isn't done in C++ at all (the C++ CSV reader has no such option, nor does Datasets) - it's done in the bindings by providing a file object wrapper that converts the encoding on the fly (e.g. [https://github.com/apache/arrow/blob/778b1772fd20766e52b2bdccbd37668726f67e0c/r/src/io.cpp#L368-L374]). This works for reading individual files, but probably doesn't work so well for datasets…I wonder if what we need is a filesystem wrapper that'll decode different encodings.

> In ARROW-15992 a user is reporting issues with trying to read in files with Latin-1 encoding.  I had a look through the docs for the Dataset API and I don't think this is currently supported.
