Please note: the end of line symbols are only used for writing.

By default, spaces surrounding an unquoted cell are treated as part of the data. In versions of Super CSV prior to 2.0.0 this wasn't the case, and any surrounding spaces that weren't within quotes were ignored when reading (and quotes were automatically added to Strings containing surrounding spaces when writing).

If you wish enable this functionality again, then you can create a CsvPreference with the surroundingSpacesNeedQuotes flag set to true (the default is false). This means that surrounding spaces without quotes will be trimmed when reading, and quotes will automatically be added for Strings containing surrounding spaces when writing.

You can apply the surroundingSpacesNeedQuotes property to an existing preference as follows:

private static final CsvPreference STANDARD_SURROUNDING_SPACES_NEED_QUOTES = new CsvPreference.Builder(CsvPreference.STANDARD_PREFERENCE).surroundingSpacesNeedQuotes(true).build();

You can also create your own preferences. For example if your file was pipe-delimited, you could use the following:

private static final CsvPreference PIPE_DELIMITED = new CsvPreference.Builder('"', '|', "\n").build();

• using a custom CsvEncoder when writing CSV (if you want complete control over how the CSV is encoded)
• using a custom QuoteMode when writing CSV (if you want to enable quotes when they're not normally required). You can use the existing AlwaysQuoteMode, ColumnQuoteMode, or supply your own.
• using a custom CommentMatcher to skip comments when reading CSV. You can use the existing CommentStartsWith, CommentMatches, or supply your own.
• ignoring empty lines (enabled by default)
• setting the maximum number of lines a row of CSV can span (useful for debugging files with mismatched quotes)
