How do I use multiple characters as field separators?

[easylinked]

In the source code, CsvReader and CsvWriter, the CsvWriterBuilder class fieldSeparator field is of type char. How can I use Tab and custom multi-characters as field separators?

[osiegmar]

A Tab character can be easily configured by CsvReader.builder().fieldSeparator('\t'). Multi-Character values (for fieldSeparator, quoteCharacter and commentCharacter) are not possible.

Why is this exact feature listed in the README if it isn't supported?
It is clearly stating that delimiters can be mixed, and even auto-detected, which also isn't the case.

Don't mix up line and field delimiters. Line delimiters (CR, LF, CRLF) are auto-detected – even if mixed. Field delimiters have to be configured (, by default) and cannot be mixed.
