Let say that I want to label the x-axis or the y-axis or added a specified title to a figure, and the statement contains an accent like ( Numéro d'iteration), I found an answer for this problem https://www.mathworks.com/matlabcentral/answers/25698-accent-as-a-character-in-a-string, but it is not working because of the sentence looks like: " Numéro d''iteration".
Any ideas how can I fix this problem?

"I found an answer for this problem "
You found an answer to a different problem: how to add an apostrophe to a char vector. Your question indicates that you are using a string, not a char vector, so that linked answer is irrelevant to your problem.

Note that strings and char vectors are different things, and so the apostrophe needs to be defined differently:
str = "d'iteration"
chr = 'd''iteration'

If you are using R2014a or earlier, getting non-ASCII characters can be difficult or tricky.
If you are using R2014b or later, then if you are using 'interpreter', 'tex' or 'interpreter', 'none', then you can directly include the characters such as é in the string. For portability because English MATLAB versions are often not UTF safe, you might want to construct the string using appropriate char() to insert the characters.
If you are using 'interpreter', 'latex' then you cannot include é and similar characters directly by using their character codes, and you have to include latex encodings of them. https://tex.stackexchange.com/questions/8857/how-to-type-special-accented-letters-in-latex
Example:
S = 'H\^otel, na\"\i ve, \`el\''eve';
xlabel(S, 'interpreter', 'latex')
