Emmanuel Bourg commented on CSV-198:
------------------------------------
I suspect this could be a UTF-8 decoding bug at the Java level, if so I'm not
sure we can fix it.
> Cannot parse file by header with custom delimiter on Java 1.6
> -------------------------------------------------------------
>
> Key: CSV-198
> URL: https://issues.apache.org/jira/browse/CSV-198
> Project: Commons CSV
> Issue Type: Bug
> Components: Parser
> Affects Versions: 1.4
> Environment: Java 1.6, Windows
> Reporter: Tadhg Pearson
>
> Reading a CSV file from the parser using the header line results in
> "IllegalArgumentException: Mappng for <column> not found" - even when the
> column exists in the file. In this case, we are using Java 1.6 and the file
> uses the ^ symbol to delimit columns. This works correctly in Java 7 & Java 8.
> The code required to reproduce the issue is below. You can find the
> optd_por_public.csv file referenced at
> https://raw.githubusercontent.com/opentraveldata/opentraveldata/master/opentraveldata/optd_por_public.csv
> It will need to be on the classpath to run the unit test. Hope that helps,
> Tadhg
> You should get the following output
> --------------------------------------
> java.lang.IllegalArgumentException: Mapping for location_type not found,
> expected one of
