This is not something you would do with Word, but rather within Windows by assigning the correct keyboard / language / region.

For instance, I use the American English / Dvorak keyboard. The letter "U" on the physical keyboard gives the letter "G" on the screen. If there is not a preset keyboard arrangement for your language, I'm sure there are utilities available to do create such an arrangement. However, the last time I experimented with such things was in the era of DOS 3.0.

Again, this is not a question about Microsoft Word. I will see if I can transfer this to the appropriate forum.
