If I do this sequence with a circle and a square, it works. However if I do it with a square and a letter it does not. How do we do this with a letter:
1) Create a square
2) Select it and do Path > Object to Path
3) Create a text letter a
4) Select the letter and do Path > Object to Path
5) Put the letter on top of the square
6) Select both the letter and the square
7) Path > Difference
The letter is not cut from the square.
Why not?
