Comma character is not being shown in the preheader

[RaulEr]

Hi community, I'm adding this line in my preheader, but the comma is disappearing, I tried using HTML entity code but nothing. Any ideas?

• Preheader line

. 

• Subject + Preheader

In the future, please include the actual text, not a screenshot. It’s impossible to troubleshoot a screenshot because no hidden/control characters are shown.

However, in this case I already recognize the problem. (It’s not a Marketo problem but a quirk of Gmail in particular; it doesn’t apply to other apps that recognize preheaders.)

The solution is to break the word up using a ZWNJ:
