Yes, using the text tool (arial font).
Then I have done a fillet at once over the complete letter, a boolean union with the circle.
I had to fight a little bit to filleting the lettre border and the circle ... it was hard to find a 'working' value ...

0.01 ... worked but a little bit to big
0.009 failed
0.002 failed
0.005 failed
0.006 !!! works :)
