The *US-International* English keyboard input locale
provides means to enter common digraph
combinations. For instance, type ' (back tick)
followed by e to enter č (grave accented e).
Console mishandles such key combinations, for the
above example it enters two back ticks then a
regular e character.
To reproduce: from the system/regional
options/input locales control panel applet add "input
language=US-English" with "Keyboard
layout-IME=United States-International" and switch
to that. Input layout MUST be "United
States-International". Then open a command line
box and experiment with digraphs. Use the following
back tick + vowel = grave accented vowel
quote + vowel = acute accented vowel
double quote + vowel = umlaut vowel
tilde + n = ń
there are a few other combinations.
When you need to enter a regular back
tick/quote/double quote/tilde just type it in once
then press the space key.
Now switch to console.exe and see that when you
enter back tick/quote/double quote/tilde it
immediately enters that key twice instead of waiting
for the second (vowel / n) key to be typed in.
