Those ASCII drawings doesn't become more sexy by converting to SVG. Use a SVG editor (or hand code it, it's fairly simple xml). Not only will it be faster then drawing using text, it will also look better.
Depending on the svg editor and font's installed, you will get mixed results and not everyone has the time or skill to write correct svg by hand. Pretty quickly you will find out that this approach creates too many problems if you want to collaborate with more than 2 people.
yeh, I hate it when people edit my hand written SVG images in a program that makes them 100x larger and unreadable. Where all they had to do was to copy one line of xml and edit coordinates.
