My Issue/Question:

When copying text into an InputText, filtering (with ImGuiInputTextFlags_CallbackCharFilter or the built-in filters) only partially works.

Blocking certain characters entirely works fine. If you try to paste text into the "imgui" text field in the demo, only the allowed characters are inserted.

The issue is that transforming characters does not work. For instance, if I type a into the uppercase text field in the demo, it gets turned into A. However, if I paste a into the field, it stays lowercase.

Minimal, Complete and Verifiable Example code:

This can be reproduced with the Filtered Text Input section in the demo.
