How to combine the \circled command on one-digit numbers and the \newcircled commands on two-digit numbers?

Question

First a MWE and its output are as follows.

\documentclass{article}
\usepackage{tikz}
%%%define circled command%%%%%%%%%%%%%%
\newcommand*\circled[1]{%
    \tikz[baseline=(char.base)]\node[shape=circle,draw,inner sep=0.3pt,text depth=0pt,font=\normalfont,minimum size=6pt] (char) {#1};}
%%%define newcircled command%%%%%%%%%%%%
\usepackage{microtype}
\usepackage{graphics}
\newcommand*\newcircled[1]{\circled{\textls[-70]{\scalebox{0.53}[1]{#1}}}}
\begin{document}
We have circled one-digit numbers and two-digit numbers by the \verb|\circled| command as follows.
\begin{center}
\circled{0} \circled{1} \circled{2} \circled{3} \circled{4} \circled{5} \circled{6} \circled{7} \circled{8} \circled{9}  \circled{10} \circled{11} \circled{12} \circled{23} \circled{68}
\end{center}
And we also have circled one-digit numbers by the \verb|\circled| command and two-digit numbers by the \verb|\newcircled| command as follows which are as desired.
\begin{center}
\circled{0} \circled{1} \circled{2} \circled{3} \circled{4} \circled{5} \circled{6} \circled{7} \circled{8} \circled{9}  \newcircled{10} \newcircled{11} \newcircled{12} \newcircled{23} \newcircled{68}
\end{center}
\end{document}

Clearly the second line of numbers are as desried. So my question is how to combine the \circled and \newcircled commands on numbers or how to produce a command which atomically uses the \circled command on one-digit numbers and the \newcircled command on two-digit numbers？

After @CarLaTeX 's answer, we can have excellent circled numbers with two-digits for footnotes, which maybe the best so far as now. The following is an MWE and its output. Note that you could use LaTeX or PDFLaTeX but not XeTeX or XeLaTeX or LuaLaTeX to compile the file since the microtype package can't be used in XeTeX or XeLaTeX or LuaLaTeX. To use XeTeX or XeLaTeX or LuaLaTeX to compile the file, you can use the fontspec package and the \addfontfeature{LetterSpace=-9.0} command instead (Cf. the third solution here).

\documentclass{article}
\usepackage{tikz}
\usepackage{graphics}%for \scalebox
\usepackage{etoolbox}%for \ifnumcomp
\usepackage{microtype}%for \textls
%%%define circled command%%%%%%%%%%%%%%
\tikzset{circlednode/.style={
    circle,
    draw,
    inner sep=0.1ex,
    text depth=0ex,
    font=\normalfont,
    minimum size=1ex
    }
}
\newcommand*\circled[1]{%
    \ifnumcomp{#1}{>}{9}{% 
        % if > 9:
        \tikz[baseline=(char.base)]\node[circlednode] (char) {\textls[-70]{\scalebox{0.53}[1]{#1}}};}{%
        % if <= 9: 
        \tikz[baseline=(char.base)]\node[circlednode] (char) {#1};}%
    }
%%%footnote number setting%%%%%%%%%%%%%%%
\makeatletter
%make footnote numbers be circled------------------
\renewcommand{\thefootnote}{%
    \raisebox{0.25ex}{%
    \scalebox{0.7}{\protect\circled{%
            \arabic{footnote}}%
        }%
    }%
}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\begin{document}
We have circled one-digit numbers and two-digit numbers by the \verb|\circled| command as follows.
\begin{center}

Use \ifnumcomp from etoolbox to test if the number is greater than 9:

\documentclass{article}
\usepackage{etoolbox}
\usepackage{microtype}
\usepackage{graphics}
\usepackage{tikz}
\tikzset{mynode/.style={
    circle,
    draw,
    inner sep=0.3pt,
    text depth=0pt,
    font=\normalfont,
    minimum size=6pt
    }
}
%%%define circled command%%%%%%%%%%%%%%
\newcommand*\circled[1]{%
    \ifnumcomp{#1}{>}{9}{% 
        % if > 9:
        \tikz[baseline=(char.base)]\node[mynode] (char) {\textls[-70]{\scalebox{0.53}[1]{#1}}};}{%
        % if <= 9: 
        \tikz[baseline=(char.base)]\node[mynode] (char) {#1};}%
    }
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\begin{document}
We have circled one-digit numbers and two-digit numbers by the \verb|\circled| command as follows.
\begin{center}
\circled{0} \circled{1} \circled{2} \circled{3} \circled{4} \circled{5} \circled{6} \circled{7} \circled{8} \circled{9}  \circled{10} \circled{11} \circled{12} \circled{23} \circled{68}
\end{center}
And we also have circled one-digit numbers by the \verb|\circled| command and two-digit numbers by the \verb|\circled| command as follows which are as desired.
\begin{center}
\circled{0} \circled{1} \circled{2} \circled{3} \circled{4} \circled{5} \circled{6} \circled{7} \circled{8} \circled{9}  \circled{10} \circled{11} \circled{12} \circled{23} \circled{68}

Good answer! Now in this way we can have excellent circled numbers with two-digits for footnotes, which maybe the best so far as now. I will post that in the final of my question. – M. Logic Apr 02 '22 at 07:39
I also post the solution here: https://tex.stackexchange.com/q/639370/140814 – M. Logic Apr 03 '22 at 06:52
By the way, what's your real name? I'd like to show thanks to people who help me a lot on Latex when writing my book. – M. Logic Nov 23 '22 at 16:38
@M.Logic I don't like to put my real name on the internet but you can find it here – CarLaTeX Nov 23 '22 at 21:20
I got it. By the way, how to pronounce your surname? – M. Logic Nov 24 '22 at 01:09
@M.Logic mʌdʒdʒɪ – CarLaTeX Nov 24 '22 at 20:27
Are there two dʒ sounds? – M. Logic Nov 25 '22 at 00:59
@M.Logic I don't know how to write that the "g" is double :D – CarLaTeX Nov 25 '22 at 05:39
@M.Logic Reading your link, I think the correct one is this: Pronunciation IPA(key): /ˈmad.d͡ʒi/ (See the section "Italian") – CarLaTeX Nov 25 '22 at 07:00
