It seems that the debugger displays the strings in the form of Ada 
string literals, which are enclosed in quotes (") and within which each 
quote character has to be duplicated (to show that it is not the 
terminating quote). So the duplication of the quotes is nothing to worry 
about. If you were to print out the strings (with Ada.Text_IO) they 
should appear just as in the input, with only the original quote characters.

However, your example also shows some extra blank spaces in the debugger 
output, for example:

Input   : Line 1 abcdef9876543210
Debugger: "Line 1 abcdef 9876543210"

There seems to be a new blank space between 'f' and '9'. Are you sure 
that you presented the input and output correctly?
