CHR$(14), actually. 53272 is one of the VIC-II's pointer registers; it's also used to set the location of the hi-res screen in the 16K bank the video chip is looking at. To make this work in the lowest 16K, the VIC-II is made to see an image of the character ROM in the middle of memory ($1000), which is where both the upper case graphics set (POKE with 21) and upper lower case set (23) originate from.
