Start with the field, not the character
Before editing, note whether you are changing your account handle, your general display name or a nickname in one server. These fields serve different purposes. Blank Unicode text is not accepted in the unique username field; the copy tool cannot bypass that restriction.
Your display name changes but a server shows another name
Check your profile inside that server. A server nickname takes precedence there, so changing your general display name does not necessarily change what server members see. Review the nickname before assuming the save failed.
Where to look for the setting
On desktop, open User Settings and look for Profiles. On mobile, begin at your profile and its edit controls. Locate Display Name for a general change, or the per-server profile for a server-specific nickname. Menu labels can vary with app versions.
You cannot edit the server nickname
Check with a server moderator about permission to change your nickname. Changing characters or generating more blank text will not grant that permission.
A copied character is rejected or looks like a box
First paste into the tool's character inspector. If text is present, copying worked; Discord validation or rendering is a separate issue. Blank-looking characters are not guaranteed to be accepted. If the result is unusable, restore a readable name.
Keep a way back
Write down your previous name before testing. Check both your profile and a conversation after saving. A blank-looking label does not hide the account behind it.
