-------------------------------
Attachment: CSV-58.patch
I have attached a new test for CSVLexer that shows how the handling of escapes
could work.

> The current escape parsing converts <esc><char> to plain <char> if the <char>
> is not one of the special characters to be escaped.
> This can affect unicode escapes if the <esc> character is backslash.
> One way round this is to specifically check for <char> == 'u', but it seems
> wrong to only do this for 'u'.
> Another solution would be to leave <esc><char> as is unless the <char> is one
> of the special characters.
> There are several possible ways to treat unrecognised escapes:
> - treat it as if the escape char had not been present (current behaviour)
> - leave the escape char as is
> - throw an exception
