Fonts.google.com not displaying space correctly in monospaced custom specimin

I posted this to the custom font text to browse if unicode is rendered properly, in a monospaced way (none?!) in the multiple monospaced fonts directory.

```
#+SEQ_TODO: ❢(i) ☐(t!) ►(r!) ▲(y) ▼(n) ⏸(p@) ☢(b@) ⧖(w@) | ✔(d) ✘(c@) ☠(k@)

| Key | Color | # |
|-----+----------+---|
| i | Purple | ❢ |
| t | DarkGrey | ☐ |
| t | Black | ► |
| y | Brown | ▲ |
| n | Pink | ▼ |
| p | Cyan | ⏸ |
| w | Yellow | ⧖ |
| b | Orange | ☢ |
|-----+----------+---|
| d | Green | ✔ |
| c | Red | ✘ |
| k | Scarlet | ☠ |
```
It seems that the tool does not use nonbreaking spaces for the rendering, and so the table above is not rendered properly.
