Details:

Using the text function with an unknown char (not displayable?), results in an
infinite loop on my machine, showing two warnings infinitely:


text(0,0,char(169))
warning: text_renderer: skipping missing glyph for character '0'
warning: called from
    text at line 170 column 10
warning: text_renderer: skipping missing glyph for character '0'
warning: called from
    text at line 170 column 10
...


This shall display the Copyright char (C), but doesn't.

It seems to be quite similiar to #55974, but I'm unsure whether the issue has
been adressed to other sub functions in plotting since I get a different
warning.
