[Joe English] tells us that, with 8.5, "the [text] [widget] uses '''TkFixedFont''' as the default [font]; which is the system-native fixed-width font.  If you want the system native text font (which is what the [entry], [listbox], and a handful of others use) by default, then: 
    [text .t -font TkTextFont]     
If you want the system-native "UI" font (used by [button]s, [menu]s, [checkbox]es, and most other UI elements): '''TkDefaultFont'''."
