Chinese Character are displayed as # when smartform is converted to pdf file

Hi All,

I have created a smartform which displays shipping address. The address contains chinese characters. While viewing the preview, the characters are displayed correctly.

The OTF form of this print is converted into PDF using the function module CONVERT_OTF and sent as mail attachment.

In the pdf attachment to the mail the chinese characters are displayed as #. Can you please provide the solution, what is causing this issue?

Regards
