Cannot find all .TTC for Myanmar MN font

Hi,

quick question: I have been asked by a graphic designer -working on Windows- to SEND HIM THE .TFF for the MYANMAR MN, Font that I used to compose the label that he will be printing soon.

Knowing that Apple Mac has it's Fonts in the User --> System-->Library-->font location, I wa sable to download a .TTC, convert it to .TTF, and send it to my graphic designer. The problem is that the .TTF does NOT include all types of fonts (BOLD, ITALIC, etc), only the REGULAR.

How can I fix this issue? are there MULTIPLE FONT folders that I need to find, in addition to the one I found? Seems that .TTF is not reading the entire family of Fonts on the MYANMAR MN font....

Thanks for a prompt response😕
