change right-arrow menu select character

[GoogleCodeExporter]

What steps will reproduce the problem?
In a grub4dos menu (text mode or graphics)
the highlighted menu entry has a right-arrow symbol at the extreme left of the 
selected menu item.

Is there a way to change this character to a space or some other symbol.
If so, can a UTF-8 symbol be specified or just a 0-FF ASCII symbol.

Alternatively, is there a patch location where it can be changed (either in 
memory or by patching grldr)

A few users have requested this.

use 0x8274 to change

0x8274 bit 23-31 ( 0x8277)

the test version can use like below 
e.g.
write --bytes=1 0x8277 0

--bytes=1 limit only write 1 byte at 0x8277,so it does not change 0x8278-0x827a

Thanks!  but in this version there is no arrow symbol by default.
For compatibility, it should be the same.
I need to use write --bytes=1 0x8277 0x10   to make it the same.

Work great though!  :-)

My code uses  write 0x8274  0   and 0x2001  to change autonumbering of menu - 
this is overwriting the 8277 value?
This breaks compatibility.
Can another location be used instead of 8277 that is unused?
