These arrows were previously drawn using the code points U+2B06 and U+2B07. The .png files for these emoji were removed in commitbfe99eband added to the Katica Regular 10 font in commitcf62d08. The emoji were not added to the bold Katica variants that are used by the table header view. The effect is that a "?" replacement character was rendered. Instead of rendering the emoji, we can draw the arrows programatically, like we do in other GUI components (e.g. the scrollbar).
