When I paste Thai characters in the edit window, they display
correctly, but in the preview window, they are displayed as question
marks. Anyone know how to correct this?
This usually means there's a mismatch in character encoding. I'd try this...
Make sure that the HTML document is saved in UTF-8. It doesn't have to
be that particular encoding but without a good reason to do otherwise
I'd use UTF-8. You can make UTF-8 the default using "Edit > Preferences
Files > Encoding > UTF-8."
Then indicate the character encoding used by your document by adding
charset meta tag to the head section:
That should do the trick. If the document is already open, you can pick
character encoding on "File > Save As" dialog.
