1) In 'Preferences', do I need to change the default 'Transfer Mode' to 'Text' before choosing to 'Edit' any remote file that is not included in the 'Transfer following files in text mode' list (before i close/save the file in the editor)?
-- eg: i'm right-clicking on 'whitelist_senders' and choosing 'Edit'.
2) If so, I did not do this the first time. Can i fix this by choosing to 'Edit' 'whitelist_senders' remote file again, and then closing/saving it again - this time with 'Text' as default 'Transfer Mode'?
Will that get rid of any weird characters the internal editor might have added when i saved the file in Automatic Transfer Mode the first time?
