CF_LOCALE top-level constant Null safety
The data is a handle (HGLOBAL) to the locale identifier (LCID) associated with text in the clipboard. When you close the clipboard, if it contains CF_TEXT data but no CF_LOCALE data, the system automatically sets the CF_LOCALE format to the current input language. You can use the CF_LOCALE format to associate a different locale with the clipboard text.
