Hi,
Is there a Matlab function to replace the special characters (like 'É') to the regular UTF-8 or ISO-8859-1?
Thanks,

"regular UTF-8 or ISO-8859-1"
Both UTF-8 (encodes all Unicode characters) and ISO-8859-1 include "É"... Perhaps you meant to ask something like "how to remove diacritics from characters?", which would match your question title.

looks like there are only manual solutions.

also it is qeustionable to do this whole thing since the change of letters can change th emeaning of the words, also in German for example, ä, ö and ü are changed to ae, oe and ue, but the same procedure does not make sence in other languages like turkish

"Is there a Matlab function to replace the special characters (like 'É')"
You can call Python from MATLAB, and it can do the heavy-lifting:
inp = 'É';
baz = @(v)char(v(1)); % only need the first decomposed character.
out = baz(py.unicodedata.normalize('NFKD',inp)) % to remove diacritics.
out = 'E'

Easy peasy.
str = 'ABCDEFGHIJKÉÉÀÀÄÄabcdefghijkl'
str = 'ABCDEFGHIJKÉÉÀÀÄÄabcdefghijkl'
strrep(str,'É','E')
ans = 'ABCDEFGHIJKEEÀÀÄÄabcdefghijkl'
If there are other special characters you want replaced, strrep will handle them too, but it looks like you would need to do them one at a time with strrep. But other tools would certainly work too. Certainly regexp, but I've never been very good at regular expressions. :) This will work though:
badchar = 'ÉÀÄ';
goodchar = 'EAA';
[u,v] = ismember(str,'ÉÀÄ');
str(u) = goodchar(v(u))
str = 'ABCDEFGHIJKEEAAAAabcdefghijkl'
