Text on a dodecahedron
Just curious.
Reading up, a little, and wondering.
Would it be possible to embed cr/lf (carriage return / line feed)
or "Enter" in the text (would Unicodes work for this)?
Something like:
"A-U000D-Partridge-U000D-in a-U000D-Pear Tree"
Probably got the syntax off.
Would something like that work?

No, right now only the text shaping level is supported (using
the harfbuzz library). This means support for ligatures, script
languages and combining characters but no layouting.
Adding a newline to the text is no problem (e.g. using chr(13))
but it will just render the glyph that's defined in the selected
font, not produce an actual line break. In most cases that will
just be a dummy rectangle, some fonts may have a special glyph.

In for a penny, in for a pound.
Here's what I'm shooting for.
It sort of works. Sort of.
Not getting the third line.

Lines 37 and 51 should be -t_height*2. The 2nd and 3rd lines are
overwriting each other.

It is always better to do a bit more structured programming to get more of

When I look at the code in my console, it ends at line 47.
So, not sure which lines you're referring to.

Code works.
How to adjust the line spacing?

If THIS:
translate([0, -t_height, h/2])
is the line you're referring to,
I changed that.
Lines 2 and 3 aren't overwriting each other anymore.
But, I now get no line 3.
So, one problem solved, I think.

Figured it out.
translate([0, (len(t)/2-i)*t_height*1.5, 0])
Thanks.
