Available font (thai) on window 8.1

software : PDF Architect 4 (standard licence)
OS: window 8.1x64 (enterprise) 
error message : All or part of the selection has no available system font. You can’t edit text using the currently selected font. 
When i use some Cordia New font in Thai language.
How can i fix.
best regards.


this usually means you are editing a PDF which only has a subset of the font embedded.
The error message is a bit confusing though, as in most cases you can still edit the text, but there might be problem with individual characters if they aren’t included in the embedded subset of the font. Did you install the Asian and extended font package?

best regards,
