Russian characters in the latex interpreter when signing the axes of the graph

I need to combine Russian characters and Latex characters in one place. Is there a solution for this? I also can't set the default text size at the beginning of the code.

close all; clc;
set(0,'DefaultAxesFontSize',24,...
    'DefaultAxesFontName','isocpeur','DefaultAxesFontAngle','italic',...
    'DefaultAxesXGrid', 'on','DefaultAxesYGrid', 'on','DefaultAxesZGrid', 'on',...
    'defaultTextInterpreter','latex');
set(groot,'defaultLineLineWidth', 2.0, 'defaultLineMarkerSize', 25)
xlabel('$\lambda$') %xlabel is $x$
ylabel('Уровень $\xsi$')
t = text(0.5, 0.5, '$\frac{1}{2 \cdot \pi} $ длина')
s = t.FontSize;
t.FontSize = 24;

Sorry, that is not possible in MATLAB itself.

It might possibly be possible in text generated through the Report Generator.... maybe... perhaps.

MATLAB's latex interpreter cannot handle characters outside of U+0000 to U+00FF .

The tex interpreter and the 'none' interpreter can handle up to U+FFFF (or some approximation to that.)
