### Changes
Disable sanitization when the UTF-8 support is enabled in the Prometheus
library.
### Usage
To enable UTF-8 support for the Prometheus exporter after this change,
set the following in your application:
```golang
import "github.com/prometheus/common/model"
func init() {
model.NameValidationScheme = model.UTF8Validation
}
```
See `exporters/prometheus/testdata/counter_utf8.txt` for an example of
the text exposition format including names/labels with dots.
