I've encountered an odd bug in pgAdmin 4 (tested on 1.6 and 2.0) on MacOS (in my case Sierra 10.12.6): when copying something to clipboard from a field in a table it begins with a char that isn't printed in most editors (including the popup when double-clicking the cell in the table to copy the string from). Neither in Notepad++ (with "show all characters" enabled), Sublime nor Intellij IDEA. In vim it shows up as <feff> and on the regular bash shell as a space - apparently it doesn't appear to happen on Windows and I just accidently shot several of my configs when I copy/pasted to a config of some java app that tried to open a connection to an OpenFire chatserver (in the logs of OpenFire i showed up during login as "???username“ rather than just "username“ ).. I’m guessing this is related to some encoding since googling suggested <feff> is a BOM (byte-order mark) - i’m not sure this is intended behavior but i may be wrong.
