JSON Output encoding issue with accented characters and apostrophes

Question

I have created a JS template with this code to output GeoJSON for our Google Maps;

{
  "type": "FeatureCollection",
  "features": [
    {exp:channel:entries
        channel="places"
    }
    {
      "type": "Feature",
      "geometry": {
        "type": "Point",
        "coordinates": [
          {longitude},
          {latitude}
        ]
      },
      "properties": {
        "name": "{title}",
        "url": "{url_title}",
        "address": "{addressline1}, {if addressline2}{addressline2}, {/if}{city}, {postalcode}",
        "icon": "/static/markers/place.png"
      }
    },{/exp:channel:entries}
  ]
}

However, some of the titles have an apostrophe or accented characters, which are being included in the GeoJSON like so;

Bar ‘67
Café and Bar

I was wondering if anyone knows how I can correct this?

Thanks

As we discus in comments, its most probable that you have this issue because server is not return correct charset (utf-8) by default. You can try next:

for apache - add into .htaccess:

AddDefaultCharset utf-8

for nginx:

charset utf-8;
