thanks

Moreover the following work for me under stable

$ convert -size 160 -pointsize 19 -channel RGBA -fill "rgb(0,0,116)"
-weight 400 -gravity NorthWest -background none \
   -flatten caption:`cat t`  est.png
$cat t | od -t x1
0000000 41 c2 a0 41 0a
0000005


Are you sure of your result ?

What is exactly the non breakable space ?
