Bugfix #26442

Very bad crashing in using "Not AA fonts" and drawing length info
on EditMesh. This uses the call BLF_draw_ascii() which apparently
corruptes then badly. Disabled the call for now, and wait for fix.

In the course of testing, added proper strlen storage for draw
in this code.

Added strlen
