Revert using wchar_t functions (9cf94d5 + 2eaf5b0). Big mistake, wchar_t is not guaranteed to be 16-bits.

@ -59,7 +59,7 @@ Other Changes:
introduced in 1.50 and broken in 1.60. (#1698, #894, #713).
- TextUnformatted(): Fixed a case where large-text path would read bytes past the text_end marker depending
on the position of new lines in the buffer (it wasn't affecting the output but still not the right thing to do!)
- InputTextMultiline(), RenderText(): Some optimization for very large text buffers, useful for non-optimized builds.
- RenderText(): Some optimization for very large text buffers, useful for non-optimized builds.
- BeginMenu(): Fixed menu popup horizontal offset being off the item in the menu bar when WindowPadding=0.0f.
- ArrowButton(): Fixed arrow shape being horizontally misaligned by (FramePadding.y-FramePadding.x) if they are different.
- Drag and Drop: Added GetDragDropPayload() to peek directly into the payload (if any) from anywhere. (#143)
