Hi,
There appears to be an encoding issue with the Cloud version of Highcharts, which is making the £Pound signs on my graphs show up as ?Question marks.
Please see this link

Strangely, when I view the graph within Highcharts Cloud, the £Pound signs show correctly, but when viewing using the embed URL, or when using the graph, it doesnt.
I look forward to some input.
