How to search for non english utf-8 symbols

Trying a very simple query on an analyzed text field and getting no results back. This is the query

GET _search
{
  "query": {
    "match": {
      "receipt": {
        "query": "₡"
      }
    }
  },
  "size": 10
}

What can I do to make this search return results with this ₡ currency symbol?

Play around with analysis. The analysis API section and the analysis section of the docs are good reads for this. You'll want to use either a keyword or whitespace analyzer or something like that.
