> As described in documentation[1], a csv format can use {{'format.line-delimiter' = '\n'}} to specify line delimiter. However, the property value is parsed into two characters "\n" , this result to reading failed. There is no workaround for now, unless fix it. The delimiter should be unescaped, e.g. using {{StringEscapeUtils.unescapeJava}}. Note that both old csv and new csv have the same problem, and both {{field-delimiter}} and {{line-delimiter}}.
