Sorting column upper and lowerstirng

Suite and Optimus Suite 5
#1

I sorted mygrid column like this:

mygrid.sortRows(1,"str","asc");

And the result:

W
GH
asdf
gh
jklé
w

Why?

#2

The “str” sorting type is case-sensitive.
But the sorting issue of the records with capital letters cannot be reconstructed.
Please, try to sort the records in the following example:

If issue still occurs - please, provide a complete demo to replicate the issue.
