Try this:
binstr = char(randi([0 1]+'0', 1, 96)); % Create (Random) Binary Character Vector
binstr8 = reshape(binstr, [], 8); % Reshape To (12x8) Character Array
binmtx = bin2dec(binstr8); % Convert Binary Character Array To Decimal Column Vector
chrmtx = char(binmtx); % Convert Decimal Column Vector To Character Column Vector
You can combine these into one line if you want to. I kept them separate to demonstrate how the code works.

chrmtx = @(x) char(bin2dec(reshape(x(:).',[],8))); % One-Line Anonymous Function Version Of This Code
Out = chrmtx(binstr);

binstr = '010010010111001101101110001001110111010000100000011100000111001001101111011000100110000101100010011010010110110001101001011101000111100100100000011001110111001001100101011000010111010000111111'
% binstr = char(randi([0 1]+'0', 1, 96)); % Create (Random) Binary Character Vector
binstr8 = reshape(binstr, [], 8) % Reshape To (12x8) Character Array
binmtx = bin2dec(binstr8) % Convert Binary Character Array To Decimal Column Vector
chrmtx = char(binmtx) % Convert Decimal Column Vector To Character Column Vector
Worked for me. What did you do differently?

One change to ‘binstr8’:
binstr8 = reshape(binstr(:), 8, []).'; % Reshape To (12x8) Character Array
and one change to ‘Out’:
Out = char(binmtx).' % Convert Decimal Column Vector To Character Column Vector
produces:
Out =
'Isn't probability great?'
Similar changes to the ‘chrmtx’ function:
chrmtx = @(x) char(bin2dec(reshape(x(:),8,[]).')).';
Out = chrmtx(binstr)
produces the same output.

Is your x a character vector, or is it a string() object? When you display it, does it show up surrounded by ' quotes such as 'abc' or does it show up surrounded by " quotes like "abc" ?

@homa maleki —
Change ‘binstr8’ to:
binstr8 = reshape(char(binstr(:)), 8, []).'; % Reshape To (12x8) Character Array
and:
chrmtx = @(x) char(bin2dec(reshape(char(x(:)),8,[]).')).'; % One-Line Anonymous Function Version Of This Code
This illustrates the problem of not having your data to work with at the outset.
