The on-canvas text tool that came in with Gimp 2.8 was a great improvement over the older Text Editor dialogue. Unfortunately many users (not all) use the on-canvas editor incorrectly.
Use the Text Tool Options to change the overall Font or color or size.... Making a selection has no effect in this case.
Use the on-canvas dialogue to only change selected characters. If you have the on-canvas off (show on-canvas editor in the tool options) then turn it back on again.
Otherwise you have to use the old text editor, which does work, but I do agree, not very convenient.
