Set mask parameter with a cell array using set_param

I would like to set a custom Simulink block's mask parameter with a cell array:
C = {'a', 'b'};
set_param(gcb, 'mask_parameter', C);
This fails because the third parameter to set_param() must be a string.
However, this works:
C1 = '{''a'', ''b''}';
set_param(gcb, 'mask_parameter', C1);
as well as
mx = [1,2,3];
set_param(gcb, 'mask_parameter', mat2str(mx));
How can I convert C to a string? I need something like cell2str(C).
Can anyone help please?

Ran in:
Here's a way to generate that C1 from that C
C = {'a', 'b'};
C1 = strrep(strtrim(char(formattedDisplayText(C))),'} {',', ')
C1 = '{'a', 'b'}'
C1_given = '{''a'', ''b''}';
isequal(C1,C1_given)
ans = logical

Thank you very much. Unfortunately I am unsing R2018b :( so I don't have formattedDisplayText(), but none the less, I though I was missing a simple internal function call.
I had to implement it using mat2str(), because my cell matrix consisted of strings that may contain apostrophes.
