Project File Encoding Conversion

Great, but... why?

File encoding is one of the most obscure encoding that I saw, and you only know what is it, when you encounter a problem. When developping in a heterogous environment, it is mostly the case that this will happen a day, or the other.

This utility is for one shot conversion, mainly in ETL processes, or can be the base of a conversion tool included in an ETL process.
