One interesting thing I discovered, at least on my F19 system, is if
highlight (copy) the Phi and then paste it into a terminal the
resulting character is a delta.
That seriously points to it being a broken font, then.
What's on the page is an instruction to print character number whatever.
Depending on what's in the font, will be what you see.
If you copy and paste the text, you're copying the data about which
(numbered) characters are there. It'd take something that copies the
data, plus the formatting, and re-applies the same formatting (and
therefor same font), for an error to be repeated.
The original poster could test that out in any editor that lets them
change fonts. Type the character out several times, and change the font
for each of them, separately. When you pick a broken font, it'll change
what it looks like.
