Problem with TTF not displaying properly

Hi All,

We have just recently updated our templates to use a new TTF font. We are a multi national office, and are running various machines in both Australia and China. We are all using windows 7. Autocad are all full versions but vary between 2010 and 2012.

We are trying to convert survey drawings from a standard font to the ttf, but for some reason, in the Chinese office only the decimal points disappear after the conversion. The same drawing when sent to the Australian office works fine and the decimal points are there. I just have no idea what to try here, as I am in Australia and can't even reproduce the issue the chinese office is having. Can anyone suggest what this might be? Happy to provide a sample drawing if needed.
Thanks!
