So, I get a capital I with a left-tilted ' and a larger size than the rest of
the font, when I use Times Regular.
I'm going to guess that you need to switch to a different font with the proper
utf glyphs in the character set.
You may or may not need to add charset utf8 to your global settings
It's all very confusing.

First of all, if you aren't already using global_settings { charset utf8 }, you
need to do so.
But it seems that *none* of the lowercase i glyphs with diacriticals display
properly, with most of the fonts I've tried. The newer generation Microsoft
fonts do work, though; try "cambria".
N.B. to jr: The fonts bundled with POV-Ray are all pure nonsense outside the
7-bit ASCII range. They are not a good test of anything.

Give "Abhaya Libre" a try, WITH charset utf8 in the global settings.

agree that the distribution fonts aren't "a good test". fwiw, two have some
usable/useful glyphs above 127, see attached.
regards, jr.

clipka said that they're "borked".
jr's table macro would be a great addition to the scripts that render all the
illustrations for the distribution - in the insert menu, etc.
Going through all of the .fon, .ttf, files and checking to see if there's a
corresponding jpg, png, bmp, and then rendering the ones that don't would be a
nice way to allow periodic updating of the font/include directory as new fonts
are added. (date, time, font name, full path) It's def a good tool to help
unravel the complex morass which are fonts and how the different versions of
POV-Ray interpret them with/without the utf8 keyword.
(That would also be a good addition: side-by-side comparison of the same font
with & without the utf8 keyword)
It's also a great way to show someone the contents of a typeface file before
they decide to hunt it down and download/install it on their system.
The chili is definitely spicy.

They are usable, sure, but they do not correspond to standard character sets.

Hi;
reason, work with Times New Roman. Anyway issue is on POV Ray treatment of some
font families.
Try this on HTML:
<style>
@font-face {font-family:pot; src: url('file:///c:/windows/fonts/times.TTF')}
div {font-family:pot;font-size:300px}
</style>
<div>
And Then this, on POV Ray:
global_settings{charset utf8}
camera{location -1000*z look_at 0}
background{color rgb 1}
text{ttf "C:\windows\fonts\times.ttf" "Ah\u00ed" 0 0
scale 700
translate<-580,-200>}
On both I'm using times new roman from Windows 10. HTML works properly but on
POV Ray you'll see that diacritic is ahead from "i".
So I think issue is on POV Ray. I'm using (it's anoying work) a combination of
"i" without dot and a separate diacritic: \u0131 and \u02ca.

I mean, I'm certainly not saying you're wrong - but I would guess that with
POV-Ray's simplistic handling of all font-related stuff, it's probably going to
be the most true-to-file interpretation.
I seem to recall some issue with Windows falling back onto backup fonts for
missing glyphs in certain character sets.
Try taking a look at the font in the Windows Character Map, or better - a 3rd
party font file viewer like FontForge. Also maybe WordPad or Notepad.
Options:
clipka had mentioned being able to copy-paste a unicode character into the
POV-Ray text editor, and the parser would correctly identify and interpret that
without any other special treatment.
Cousin Ricky and I have manually converted the character definitions into Bezier
spline objects.
You could dissect the body of the i and the diacritical using masks / CSG and
define a custom made character as an object {}
Use just that character from another font that sufficiently resembles Times.
Use a browser or word processor and screenshot the correctly displayed text and
use that as an image_map billboard with a transparent background.
POV-Ray was really designed as a graphical raytracer, not as something that
handles a lot of text like a word processor.

Have you set the correct charset in global settings?
See: https://www.povray.org/documentation/3.7.0/r3_4.html#r3_4_1_6

P.S.: https://www.povray.org/documentation/3.7.0/r3_3.html#r3_3_2_7_2
does not mention how characters beyond the BMP are handled at all.

\u02ca ist the wrong character. It is a "spacing" letter, not a
"combining diacrticial mark" (which are intended to be combined with a
letter).
See:
https://en.wikipedia.org/wiki/Spacing_Modifier_Letters
vs.
https://en.wikipedia.org/wiki/Combining_Diacritical_Marks — where the
"combining acute accent" is at U+0301.
