Returns the conversion path of ec.
The result is an array of conversions.
Example
ec = Encoding::Converter.new("ISO-8859-1", "EUC-JP", crlf_newline: true) p ec.convpath #=> [[#<Encoding:ISO-8859-1>, #<Encoding:UTF-8>], # [#<Encoding:UTF-8>, #<Encoding:EUC-JP>], # "crlf_newline"]
Each element of the array is a pair of encodings or a string. A pair means an encoding conversion. A string means a decorator.
In the above example, [#<Encoding:ISO-8859-1>,
