Yes, the built in PDF converter has trouble with some fonts.
You can swap the font for something else but if that is not an option try printing to an external PDF converter.
There has been a problem with older fonts for some years.
Something to do with the way they are created - spacing between characters.
I have found certain characters or combinations of characters causes the problem.
Finding a new font (similar style) or having the old font repaired with a program like Trans Type Pro or maybe Font Doctor can also be a solution.
Here is a link to an old post.
