Team's Response

It is an intended behaviour as we accept the following for telegram: Telegram handle must be minimum 5 characters and maximum 32 characters. It can only contain alphanumeric characters and underscores.

Hence, capitalization are treated differently, as it should be clear that alphanumeric characters means capitalizations are treated differently.
