Title: Fix character encoding issue when saving for csv

The existing code assumes by default that the encoding is 'UTF-8', causes a bug when trying to parse inputs from CSV for the character ü, in the word für.

Say my machine's input is ISO-8851, then iconv would have suppressed and truncate the string as 'ü' is not a valid charset of 'UTF-8'.
