This is a BUG REPORT on Yahoo Webnail on Desktop.
Yahoo WEBMail does not display this PDF file. Instead I get gibberish.
Other browsers (Opera, Chrome, Firefox) do succesfully display the PDF.
The workaround is to download the file and view it with a PDF Reader. (I use Adobe Acrobat DC)

It occurs with PDF generated by ID Mobile in UK.(I can submit a copy when requested)
Here is the properties of the file:
