Github user greghogan commented on the issue:

@fhueske, I refactored `DelimitedInputFormat` and `GenericCsvInputFormat`
to reinterpret the fields whenever the charset encoding changes, and also
updated the test per your review.
> StringParser not specifying encoding to use
> -------------------------------------------
>
> Key: FLINK-3921
> URL: https://issues.apache.org/jira/browse/FLINK-3921
> Project: Flink
> Issue Type: Improvement
> Components: Core
> Affects Versions: 1.0.3
> Reporter: Tatu Saloranta
> Assignee: Rekha Joshi
> Priority: Trivial
>
> Class `flink.types.parser.StringParser` has javadocs indicating that contents
> are expected to be Ascii, similar to `StringValueParser`. That makes sense,
> but when constructing actual instance, no encoding is specified; on line 66
> f.ex:
> this.result = new String(bytes, startPos+1, i - startPos - 2);
> which leads to using whatever default platform encoding is. If contents
> really are always Ascii (would not count on that as parser is used from CSV
> reader), not a big deal, but it can lead to the usual Latin-1-VS-UTF-8 issues.
> So I think that encoding should be explicitly specified, whatever is to be
> used: javadocs claim ascii, so could be "us-ascii", but could well be UTF-8
> or even ISO-8859-1.
