Couple things I noticed in using Gretl on my Mac. 

First is it localized to Japanese for some reason on install. I was able to poke around and change it to English. My system is in English and so not sure why it didn't read that correctly.

Second I noticed that there was recently code added (07/23) to handle quotations on importing CSVs. I have a CSV with names in it and some names have quotations (like O'Brien). For now I can delete that column but perhaps worth adding an option to ignore quotations.

Thanks,
