Most of us use Bootstrap Datatable in our projects. I'm sure our child has come across a situation where the up and down arrow icons are broken. Sorting arrows (like â†) appear. When we do CTRL+F5 in the browser, he saw that it was fixed. Even though we have downloaded it, when we refresh it with normal F5, we see that it is loaded corruptly again. Even though it is a charset problem, you can follow the steps below for a definitive solution.
content:' \25BC';
content:' \25B2';
Now our arrows will appear correctly and the character problem will be gone.
