Don't do ugly stuff inherited from the texts created for the blanks on a historical mechanical typewriter. Use
TextBox
, which is implemented as the text
<input>
element:

^].
Also note that for all non-ugly fonts, the number of characters (spacer or not), it pretty much irrelevant, because they are not
monospace, different texts with the same number of characters take different space.
