Add correct autodetection of different UTF encodings of imported CSV files
Ivan is very quick finding and proposing his solution. In addition he implements the best solution directly after agreement. Likely he has tested the solution in advance because the implementation works in one time flawless. Thanks Ivan and hope to see you on our next project.

Another CSV encoding autodetection task
I had a headache solving a problem with reading badly formatted files containing foreign letters programatically. Ivan quickly helped me solve my problem, and gave great feedback as to what the actual challenge was. In addition to getting my problem solved, I gained valuable insight for use in later cases if or when I run into similar issues. Great work, thank you very much!
