Where do the breaks in certain combinations of letters come from?

Question

Google

and

For headings I use the font "Play" from the service "Google Fonts". Suddenly I noticed that with certain combinations of letters, some unexpected indents appear (yes, yes! These are not spaces in the code). From the first screen, you can see that this miracle occurs everywhere in the same combinations of letters (respectively, where the "Play" font is used). As soon as I reset the font to standard Arial in Firebug, this jamb disappears. Please tell me who knows what could be the problem with these Google Fonts?
I don’t know how this will help, but here is the header design code:

font-family: Play;
font-weight: 400;
font-style: normal;
letter-spacing: normal;
text-align:center;

Wrote words in which you had problems. As you can see from the example, there are no problems. Try to look for the problem not through the firebug, but look in the source code, maybe some characters are not displayed.
