seems that when you copy and paste, sometimes there’s a question mark in a box replacing letters, particularly t or ti in some strange unicode error. but why in my experience does it only affect these characters?
In: Technology
Since pdfs were never intended for editing, but to send files extremely accurately to printers no matter which system, a generated pdf will not rely on installed fonts on your system, but embed them in the pdf file, this also allows any letter combinations that are commonly connected in many typefaces, like ti or similar to not be stored as individual t and i letters but rather as a combined symbol for ti.
When you copy and paste that text into a text box expecting standard asci or Unicode symbols, it won’t have a ‘picture’ for that ti symbol to display, and default to the box to show that there is a symbol supposed to go here, but the system has no font installed to display it.
