I can't seem to reproduce what you are describing. If I select the text tool with the default settings, enter C G Am F and then either tap way or tap the X to close the annotation editor, I see all of the characters I entered. If you tap the text tool twice to view the settings, what settings have you changed from the defaults? What size do you currently have selected? Also, what type of device are you using?
