GDB/MI Output Formats

[Marco Menegazzi]

Hi, 
I would like to know if there is a corrispondence in gdb/mi for the command print/u. 
My problem is that if I use p/u the output format is right but every time it find a " (double quotes) it goes to a newline.

~"$5 = {"
~"type_size = 0, "
~"count = 0, used = {"
~"0, "
~"0, "
~"0, "
~"0, "
~"0, "
~"0, "
....

if I use -data-evaluate-expression instead I can't change the output format to unsigned int as with the print.
Any ideas? 
Thank you.
