I have seen similar issues raised with poor answers, so let's see if we can't solve this:
In trying to add some typewriter-style text (the Add Text tool / Typewriter) as an overlay on an image...some fonts work fine but others that I have installed in my system (Windows 11) that are truetype fonts simply do not show up properly, instead using some default font like Arial.
Note that these same fonts DO show up fine if I use the simple text option, the one that has the WYSIWYG text editor, so now it feels very strange and buggy. The typewriter tool editor just has a simple text entry line, not the fancy editor where I can style the text, and it seems to create a video clip, not an 'image' for the text.
What is going on here? Why does the typewriter option fail to use the font I have selected? As mentioned, it does show up fine for some fonts, but not others. And, of course, the font I want to use is not showing up and displaying properly. Truth is I like the typed letter look, not just a block of text that scrolls into view, hence my frustration that I can't get it to work reliably.
