> ISO-8859-1 encoding doesn't work for text format

> Key: SPARK-38801

> Project: Spark
> Issue Type: Bug
> Components: Spark Core

> 3.2.1, scala 2.12)
> Reporter: Himanshu Arora
> Priority: Major

> When reading text files from spark which are not in UTF-8 charset it doesn't
> work well for foreign language characters (for ex. French chars like è and
> é). They are all replaced by �. In my case the text files were in ISO-8859-1
> encoding.
> After digging into docs, it seems that spark still uses Hadoop's
> LineRecordReader class for text format which only supports UTF-8. Here's the
> source code of that class:
> [LineRecordReader.java|https://github.com/apache/hadoop/blob/trunk/hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-core/src/main/java/org/apache/hadoop/mapreduce/lib/input/LineRecordReader.java#L154]
>
> You can see this issue in the screenshot below:
> !image-2022-04-06-09-30-21-751.png!
> As you can see the French word *données* is read as {*}donn�es{*}. The work
> *Clôturé* is read as {*}Cl�tur�.{*}{*}{*}
>
> I also read the same text file as CSV format while providing the correct
> charset value and it works fine in this case as you can see the screenshot
> below:
> !image-2022-04-06-09-31-45-062.png!
>
> So this issue is specifically for text format. Therefore reporting this
> issue.
