Android: Asian fonts don't render in PDF viewer or print preview

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Obtain test file "j12.pdf" by ordering item IT-3011A "Standards of Printer 
Evaluation pattern" from here 
http://www.jeita.or.jp/cgi-bin/standard_e/list.cgi?cateid=8&subcateid=45
The test file is on the included CDRom.
2. On an Android phone with "M" installed, open J12.pdf with Adobe Acrobat 
Reader

What is the expected output? What do you see instead?
Expect file to display correctly.  Instead some graphics appear and no fonts 
are rendered.

What version of the product are you using? On what operating system?
Google Android "M".

Please provide any additional information below.
Also test with Drive PDF viewer - More graphics are displayed but no fonts 
render
Also attempt to print - preview shows same result as printing app.

I've attached several screen caps:
pc.png - viewed on a PC with Asian font pack installed
android_acrobat.png - viewed on Adobe Reader on Android M
android_drive.png - viewed on Drive PDF viewer on Android M
android_print_preview - viewed using Adobe Reader then print preview on Android 
M

To be clear, is this bug about Adobe Acrobat Reader on Android?

I'm not exactly where the rendering happens, whether that's part of the Reader 
or the OS, but yes, you open the file in Acrobat and the fonts don't render. 
You print and they don't render in the preview nor on paper.

Currently no PDF documents can be opened in Drive/Preview 3 so I can't verify 
whether this issue also appears in the Drive viewer.  Please verify on your end 
if Drive shows the issue. I've attached a freely distributable file that shows 
the issue as well as screen caps of the file in Acrobat on both Lollipop and M. 
 We have verified that these fonts are missing from Android M -
- MTLmr3m.ttf (MotoyaLMaru-W3-90ms-RKSJ-H)
- DroidSansFallbackFull.ttf

I think you should file a bug against Android instead. We can't help you with 
Adobe Acrobat + Android M. PDFium isn't even involved here.

It also repros on the Drive viewer.  Does that make it a PDFium issue?

I have no idea if the Android Drive app uses PDFium to view PDF files. Why 
don't you file a bug against Android and go from there?

Please ignore acrobat reference. Believe this is a PDFium bug as we have seen 
the same reported for Drive PDF reader and Android printing framework in L and 
M. Seems like there are issues with rendering certain documents in Japanese.

Sure. we can try to fix the PDFium + Android issues, but the Acrobat + Android 
issues are still beyond the scope of this bug. We don't have good Android test 
coverage right now since we have been concentrating on the desktop.
