Rendering issue for complex script with embedded TTF fonts

[srn123]

Hi,

I have a PDF with a mix of English and Tamil (an Indian script) in which I notice that there is a problem in rendering the Tamil portions with PDF-Xchange Viewer. The same file renders correctly in Adobe Acrobat Reader X, Google Chrome PDF Viewer and Sumatra PDF Viewer.

I am using version 2.5 (build 201.0) of PDF Xchange Viewer on Windows XP, SP 3. I have the option "Install files for complex script ..." enabled in Regional and Language Options of Control Panel.

I notice that the embedded font for Tamil is TrueType in the document and certain characters are not rendered properly (those with a dot on top of them). I do not have the source ttf file of the embedded font.

I cannot share the entire content of the PDF in the forum as it contains personal information, but can share with developers if required. Please let me know of the e-address to where I can share the source PDF.

I am enclosing the snapshots of a portion of the PDF doc as rendered in different viewers.

Regards,

srn

Stefan,

Thanks for the prompt response.

Of all the forums that I lurk in, this is the one where the forum moderators are prompt to the point of being perfect. Great product and a wonderful crew manning it. Way to go!
