This works, the legends shows up fine: var chart_url = 'http://chart.apis.google.com/chart?' + 'cht=bvs' + ...some other stuff... + '&chdl=Lowest price|Average price'; This doesn't work, the legends don't show at all: var chart_url = 'http://chart.apis.google.com/chart?' + 'cht=bvs' + ...some other stuff... + '&chdl=L' + unescape("%E4") + 'gsta pris|Genomsnittligt pris'; Any ideas?
