Right now parser assumes UTF8 encoding but file can be encoded differently. This RFE is to add in flight conversion.

Scope of work:

a. Define new parsing flags to request conversion
b. Process the flags when parser is initialized
c. Consult the flags and call iconv after line is read from file to do the conversion
d. Make sure the iconv is properly initialized and cleared (TBD whether it should be done per line of for the whole file. If letter it should be properly cleaned in success and failure cases.
e. Add unit test
