Problem with hyphen in pdf from indesign

[#1]

I have now in several different documents had the same 
problem that some words, at the end of a sentence and 

with a hyphen, in the exported pdf, appear with a strange sign. 

I don't see this sign in indesign, but in the pdf it's clear. What is this cause?

What font is it? Does it only happen with this specific font?

It looks like it may not have embedded correctly. Deleting it entirely from your system, and re-installing it might fix this.

I have the same problem, did you find a solution yet?

No, I never solved the problem, and still have it with many different types of font;(
