[Tex/LaTex] How to use new unicode characters

input-encodingspackagestexmakerunicode

I know, there are lots of questions about Unicode and I've read a lot of these. But I wasn't able to solve my problem:

I have to use the characters ↊ and ↋ (U+218A and U+218B) in my text. I tried with LaTeX and XeLaTeX and several packages. But it always sais

! Package inputenc Error: Unicode char ↊ (U+218A)(inputenc) not set up for use with LaTeX.See the inputenc package documentation for explanation.Type H for immediate help….

What can I try? How can I set it up for use?
I'm using Texmaker on windows 10 with MikTeX.
Thanks!

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{graphicx}

\DeclareUnicodeCharacter{218A}{\turnedtwo}
\DeclareUnicodeCharacter{218B}{\turnedthree}

\makeatletter
\DeclareRobustCommand{\turnedtwo}{\make@turned{2}}
\DeclareRobustCommand{\turnedthree}{\make@turned{3}}
\newcommand{\make@turned}[1]{%
  \raisebox{\depth}{\scalebox{-1}[-1]{#1}}%
}
\makeatother

\begin{document}

123456789↊↋0

\end{document}

Not sure whether this renders correctly, so I provide also an image of the code.

Output for the test file:

Prompted by comments, here's a version that works with all engines. I only provide the image of the code, because just a few fonts sport the glyph (among them, Fira Code).

As suggested in the comments, you could set your font to one that supports Unicode (this solution requires XeLaTeX):

\documentclass[12pt]{article}
\usepackage[a4paper]{geometry}
\usepackage{fontspec}

\setmainfont{Arial Unicode MS} % Other fonts that might work: Hiragino Maru Gothic Pro, Lao Sangam MN, Inaimathi, Microsoft Sans Serif

\begin{document}\huge

\noindent a b c \\
◌ \\
ä ë \\
à è \\
ç 

\end{document}

If you save your test file in UTF-8 encoding then it will run without error. If you save it in latin1 (iso-8859-1) you get the error

! Package inputenc Error: Unicode char ónpr (U+153)
(inputenc)                not set up for use with LaTeX.

See the inputenc package documentation for explanation.
Type  H <return>  for immediate help.

with current latex, or the slightly less readable but equivalent error message that you showed, on older versions of LaTeX.

So you can re-encode your file by saving it in utf-8 or declare to latex that it is in latin1 by changing the line to

\usepackage[latin1]{inputenc}
