Sort repetition in text

I'm trying to sort a string of letters into repetition of each letter.

for example:

Text= 'KKKKLLOOKkl';

Result should be {'4K','2L','2O','1K,'1k','1l'}

1. Text could be any length.
2. Text could be only alphabet letters (capital and small).
3. Result could be any type of array (vector/ table/ cell ect).

I used 'unique' to get which letters are inside Text but how do I count the repetition for each occurence?

Is there a fast way or a function instead of looping for each result of unique?

Text = 'KKKKLLOOKkl'; 
[C,~,Xz] = unique(Text,'stable')

C = 'KLOkl'
Xz = 1,1,1,1,2,2,3,3,1,4,5

Thanks for any help :)

Text = 'KKKKLLOOKkl'; 
[C,~,Xz] = unique(Text,'stable');

idx = [true; diff(Xz) ~= 0];
strcat(sprintfc('%d',diff([find(idx); numel(Text)+1])),C(Xz(idx)).').'

ans = 1×6 cell array
    {'4K'}    {'2L'}    {'2O'}    {'1K'}    {'1k'}    {'1l'}

T = 'KKKKLLOOKkl'; 
D = [true,diff(T)~=0];
L = diff(find([D,true]));
C = compose('%s%d',T(D).',L(:))

C = 6×1 cell array
    {'K4'}
    {'L2'}
    {'O2'}
    {'K1'}
    {'k1'}
    {'l1'}
