Need Help. Page View (and PDFs) in Paginated Reports not rendering spaces

Hello all.  I've got a paginated report that's reading from a Power BI dataset.  It's reading some data in plain text from a SharePoint site and when I run it in report builder or online it looks fine, but if I put it in Page View or save as PDF, the spaces "dissapear" for some fields in some places unpredictably.  When I copy the text and paste to notepad, the space are there.  When I check the ASCII of those spaces it's the standard 32 space.  We tried swtiching fonts out, including looking at a courier font.  No help - same symptoms.  We tried re typing the data in the list and refreshing everything - same symptoms.  

Anyone seen something like this before?
