Fixed width file search based on position value

I am unable to find the right option to extract the data in the fixed width file.

sample data 

hujk9876       io xgla
dkfj9098           dja

Search based on position 8-9="xg" and print the entire row

The position of "xg" is 9-10 despite the phrasing in the spec. Try
$ grep -E "^.{8}xg" file

$ sed -En "/^.{8}xg/p" file

Dear ctsgnb,

What a fantastic and concise coding technique. I've fought with this for years, often cobbling some terrible script round it.
