If non-English characters are missing when you export text to
PDF
files, you need to install the Arial Unicode MS font.
When you save a drawing document as a
PDF
file, and the drawing contains non-English (non-ASCII) characters, the appropriate fonts
must be available to render the characters. If the specified font is not installed on
your computer or does not support Unicode character glyphs, then the Arial Unicode MS
font is used.
Arial Unicode MS font is available for purchase online.
