Download button has weird space in between o and w

### Bug Report

| Q | A

| BC Break | ?
| Library Version | N/A (not used by myself)
| PHP version | N/A (not used by myself)

#### Summary

There seems to be some odd rendering behaviour with this PHP library and using letters such as "W".
When using those is there a weird gap before the letter itself.
This is prominently visible in this project's readme, by looking at the "downloads" badge, which displays as "do wnloads"

Here's an image of what I mean.

Using shields.io directly (i.e. https://img.shields.io/badge/downloads-16.9%20k-blue) doesn't show this specific issue, so it must be a cause by this library.

This was originally reported to https://github.com/antonkomarev/github-profile-views-counter/issues/26

I use Edge as browser to view these badges, so if it doesn't show on Chrome (Probably unlikely as Edge also uses Chromium), Firefox, Safari, etc. could it be a browser-specific issue.

#### Current behavior

The badges have random gaps (mostly before a W) for no apparent reason.

#### How to reproduce

1. Use this library to generate a badge I guess.

I don't really use this library myself, so I can't give clear steps to reproduce. It's just something I noticed and wanted to report.

#### Expected behavior

The badge should look like the example I provided:


Start by reproducing the README's "downloads" badge in Edge and compare it with the direct shields.io example linked in the report. Inspect the badge-generation or rendering path responsible for the text spacing; the issue is done when the generated badge no longer inserts gaps before letters such as W across the relevant browsers.
