Weird character in front of Highcharts tooltip series names

Question

I have a Highcharts chart which is, for some reason, showing odd characters before the series title only on the data point pop up. I am using the default popup and highcharts 4.0.1. I currently set all series to have the title `hi` to ensure nothing in my code was messing this up. Also if I output `countsGraph.series[0].name` I also get `hi`. What is causing this? Unfortunately I cannot make a fiddle at the moment as my access to HighCharts.com is playing up. Here is how I create the series ``` // Create new series if requried if (!series[c]) { series[c] = { name: "hi", data: [] }; } ```

Accepted Answer

Most probably you are using different coding than UTF-8. You can simply remove that character, by changing `pointFormat`, from: ``` \u25CF {series.name}: {point.y}
``` to: ``` {series.name}: {point.y}
``` Or, as just `@Adam Goodwin` pointed out, set default format in your options: ``` \u25CF {series.name}: {point.y}
```
