Changes

* If the {{Code|header}} option is set to {{Code|true}}, the first text line is parsed as table header, and the . Instead of {{Code|<entry>}} elements are replaced with , the field names:** Empty header names are represented by a single underscore ({{Code|_}})encoded, and characters that are not valid as described in element names are replaced with underscores or (when invalid as first character of an element name) prefixed with an underscore.** If the {{Code|lax}} option is set to {{Code[[Conversion Module#Keys|false}}, invalid characters will be rewritten to an underscore and the character’s four-digit UnicodeConversion Module]], and underscores will be represented used as two underscores ({{Code|__}}). The resulting element names may be less readable, but can always be converted back to the original field names.
