Using the website at export link below, sometimes the species_guess column has random incoherent symbols. I haven’t done any searching to see if there is a pattern with what observations have this error and which do not, but they seem to be consistent from one export to the next where the same observation has the same symbols. This is certainly an encoding error of some sort. Out of my 1000 most recent observations, 18 had this error

Using this string the first row should display this error

in notepad
Curiously, throwing the Chinese characters into google reveal that it is the Chinese common name of the observation. How the heck did that get into a column of latin names?
