Delete array elements with Coder compatibility

I need to delete elements of a string with compatibility for Coder. For example:
myStr = 'This is a fun problem!'
myStr(10) = '';
Now this works just fine in Matlab, but I get an 'The right and left hand sides must have the same number of elements' error when I try to use Coder at the 'Check for Issuse' stage. I realize that I could do the following,
myStr = 'This is a fun problem!'
myStr = myStr([1:9,11:numel(myStr)]);
but this is ugly and challenging because I am doing this as part of a loop where the indexes would get complicated quickly.
Any ideas? Thanks.

Interesting. I thought Coder would take issue with this, as I thought [] was an empty numeric array. Thanks for the help.

Figured out a solution. Redefine the string use logical indexing to select all but the element you want to exclude.
myStr = myStr(1:numel(myStr) ~= 10)
