Some textbox contents garbled when populated via code

[Ric Hardacre]

We have a bank of PDF templates containing textboxes that are populated via code, then set as readonly. Since upgrading to V25 certain fields are now corrupt after filling in. There doesn't seem to be a pattern to which text boxes get corrupted but it is consistent (as in the same field is corrupt each time). Attached are two PDFs with one or two corrupted fields each. 



Interestingly if - when viewing in Adobe PDF - I click on the corrupt text as if to edit it (Even though the field is readonly) it appears correctly (note the text editing carat in the middle of the word Southampton):

Attached is the template PDF.

Edit: I've worked out that the garbled text is in fact sort of correct but offset by 29 decimal. E.g. the first two legible chars in the screenshot are "RI" = (82,73) ASCII, add 29 = (111,102) = "of", which is what it's supposed to be!

Edit 2 : Have tried with latest version of Syncfusion via nuget: (Project is ASP .Net 4.8 - MVC 5)

Syncfusion.Pdf.AspNet.Mvc5.25.1.39
