The available characters are listed at https://en.wikipedia.org/wiki/Malayalam_(Unicode_block) . They start at U+0D00 which is char(3328) for the first entry.
The way to read the file to get the unicode depends upon exactly how the file was stored. Sometimes the method can be quite simple, but until you know which encoding is being used you have to be more careful. See https://www.mathworks.com/matlabcentral/answers/267176-read-and-seperate-csv-data#answer_209938 for some code of mine that figures out how a documented has been encoded.

audiodir = 'C:\Users\NeeK\Documents\MATLAB\EE403\Final Project\malayalm\wav'; %adjust as appropriate
[filename, pathname] = uigetfile('*.txt', 'Choose a text file');
if ~ischar(filename)
fprintf('Cancel!\n')
return; %user cancel
end
fullname = fullfile(pathname, filename);
[fid, msg] = fopen(fullname, 'r', 'n', 'UTF8');
if fid < 0
error('Failed to open file "%s" because "%s"', fullname, msg);
end
S = fread(fid, '*char', [1 inf]);
fclose(fid);
if isempty(S)
fprintf('Text file "%s" is empty!\n', fullname);
return
end
if S(1) == 65279; S(1) = ''; end
audio_data = [];
fs = 1;
for thischar = S
basename = sprintf('%04x.wav', thischar);
this_filename = fullfile(audiodir, basename);
if ~exist(this_filename, 'file')
fprintf('audio file "%s" not found, skipping character "%c"\n', basename, thischar);
else
[thissound, fs] = audioread(this_filename);
if isempty(audio_data)
audio_data = thissound;
else
oldchan = size(audio_data, 2);
newchan = size(thissound, 2);
if newchan < oldchan
thissound(end,oldchan) = 0;
elseif oldchan < newchan
audio_data(end,newchan) = 0;
end
audio_data = [audio_data; thissound];
end
end
end
