What is an undisplayable character captured?

crawled a string info_content, on the web page but printed it out one by one and found that it contained a character that could not be displayed. What is this character? It doesn"t seem to be that "n"
reported this error when converting with int ()
ValueError: invalid literal for int () with base 10:"n"

print (info_content [1:15])
for i in range (0br 15):
print ("index", I, ":", info_ content [I])
if (info_ content [I] = r "r"):
print ("get")
