some pdf files cann't be displayed correctly in PDF-XChange

[naughtywl]

I found the cann't recognise some pdf documents,I put a test file as attachment here. The file name and its content is chinese.I very want the PDF-XChange Viewer as my default PDF viewer. So I really hope who can fix it.By the way Acrobat reader can display the file correctly.

Hello naughtywl,

It appears that there is some problem with the file. I got dots instead of text when I tried to open it in Adobe's Reader as well.

Best,
Stefan

The test file name is chinese.When I upload the file,the file name is truncated,Maybe the forum doesn't support chinese file name attachment.

Hello naughtywl,

Yes I can see the name as ".pdf" but my comments were for the contents inside, and that I could not see the text inside correctly with Adobe's Reader as well:


Best,

I believe this is a font issue.

I can see the Chinese in both PDF-XChange and Adobe. Adobe does however complain about one of the fonts. As you can see these fonts are not all embedded.



This means you need to have the font installed on your PC to see them. Both our Viewer and Adobe Reader will do it`s best to substiitute the nearest available forn but this does not always have an ideal result. The best way to ensure that a document will look as you intended is to embed the fonts. The down side to this is that the file size will be increased.

In my computer,the corresponding pictures are uploaded as attachment(I don't know how to paste a picture along with my words :>),the font imformation is in fontproperty.png.And the other pictures are the display of pdf readers.Each for Adobe reader, PDF-XChange Viewer,Foxit Reader.Thanks

Hi naughtywl,

there may be some font substitution going on here. I'll see if I can get a more detailed answer from one of our dev team experts. Please bear with me.

Your file uses non-standard extensions for CJK fonts.

It is not documented in PDF specification and cannot be used on any computer with a different OS locale (therefore we cannot see normal text here even in Acrobat - our OS are not chinese and have no corresponding fonts, both things are important).

Foxit Reader is developed in china, so it has support for such files as a work around which is not unexpected. The Current version of the PDF-XChange Viewer (2.x) will not support such files, however we will see what can be done in V3 to support this if at all possible.
