Probably worth adding a test for the slightly more complicated 'Host details by process name' custom URL, which uses host.name and process.name:

      {
        "url_name": "Host Details by process name",
        "url_value": "security/hosts/ml-hosts/$host.name$?_g=()&query=(query:'process.name%20:%20%22$process.name$%22',language:kuery)&timerange=(global:(linkTo:!(timeline),timerange:(from:'$earliest$',kind:absolute,to:'$latest$')),timeline:(linkTo:!(global),timerange:(from:'$earliest$',kind:absolute,to:'$latest$')))"
      },

Tested a custom URL on the special characters data set and am seeing this error when opening a link to Dashboard:

Job config has:

  "analysis_config": {
    "bucket_span": "15m",
    "detectors": [
      {
        "detector_description": "mean(\"metric%$£&!{(]field\") partitionfield=\"at@name\"",
        "function": "mean",
        "field_name": "metric%$£&!{(]field",
        "partition_field_name": "at@name",
        "detector_index": 0
      }
    ],
    "influencers": [
      "at@name",
      "singlequote'name"
    ]
  },

And opening a URL which uses the influencers from this anomaly:

I think it is the singlequote'name field name which is causing the problem here.
