add Chinese support in cfdocument pdf output with the flying saucer engine

Description

`<cfdocument type="modern">` which uses the flying saucer engine to render pdf has problem displaying Chinese as the underlying code uses CP1252 codepage by default causing the rendering of the Asian language to fail. The pdf will be produced with no exception, however, the Asian language characters cannot be seen.

A possible fix has been provided by gaia-jyh can be found here, accompanying reproduction code:

I've checked this ticket with the latest PDF version 1.1.0.7-SNAPSHOT in lucee version 5.3.9.120-SNAPSHOT. Now the Chinese fonts are rendered on pdf with the fontDirectory attribute.

For now, no other patch to this. Hope the PDF extension will be available with the above patch soon.

will this be fixed in 5.3.9 or is the patch here still needed for Chinese text to display?
