Background: txt files users send can be in many different encodings.

EVSS only accepts ASCII encoded text files. ASCII is a basic encoding that allows for 128 characters.

In the instances that failed, so far I've found Windows-1252 and macRoman encoded files.

There is no 100% correct way to automatically determine a txt files encoding, but to properly convert a txt file to the ASCII encoding evss accepts, the encoding of the files needs to be known.

Going to try to make a guess if I can, otherwise provide a best effort conversion that may not be perfect, but it should be readable. For example "I'm" might turn into "I?m". In general, Letters and Numbers will translate clean...
