combine multilingual values in the same column to 1 value

Hi, I have a column with different answers for the same value, like multilingual answers:

'Goed', 'Gut' and 'Good' means the same and they have the same value (5 in the scale 1 to 6)

I want to combine these values values into 1 value ('Goed') while showing the results in my grahs (and not different bars for Goed, Gut and Good)

Do do i do this???
