The solution of bearophile only needs 2 small modifications to handle this:

#=========================================
data = """
%HEADER
title1 = "Untilted1"
username = "User1 20 %"

%DATA
title2 = "Untilted2"
username2 = "User2 10 %"
"""

# Ensure data starts with a newline
data = '\n' + data

# Split using '\n%' instead of '%'
l1 = (p.strip().splitlines() for p in data.split("\n%") if p.strip())
result = {}
for part in l1:
     pairs1 = (pair.split('=') for pair in part[1:])
     pairs2 = ((k.strip(), v.strip().strip('"')) for k,v in pairs1)
     result[part[0]] = dict(pairs2)
print result
#=========================================
