Bold caracter aren't bold if exported to .pdf

When i export pdf or simply check them into the vault, the pdf created does not show bold character the way they are in my drawing.

I tried playing with the save as option but it makes no difference.

When i print these drawing i get good results, even if i print them to PDF they are good.

Any idea how i could solve this?

Thx!
