Convert 1997 SR data.csv from latin1 to utf8

This is the same operation performed in vim, this time for Chapter 6.
I detect errors at the time of import of facts in MySQL:

ERROR 1366 (HY000) at line 33:
Incorrect string value: '\xEDa (Me...' for column 'value' at row 13299

I then locate the line in import.sql (generated in ipcc-facts-import
project) with following command:

head -n $((33+1+13299)) import.sql | tail -n 1 | xxd

where 33 and 13299 are the line number and row reported in MySQL error.
