Created attachment 366584 [details]
blank United Kingdom tax return form

The UK tax return form shows jumbled text when opened in Evince 3.18.2. It displays normally on Mac OS X with the default viewer, and I assume it does on Windows.
The jumbling starts on page 3, with odd;y-spaced commas replacing most, but not all, text. The page footer is replaced with random letters.
On page 6, the footer is back to normal, but all the body text is replaced with random letters and numbers.
The file is a fillable form. The problem was first noted with a copy containing my personal data. The attachment is a blank copy that also shows the problem.
