printing funny symbols within spyder ide

[andy]

when printing these 'escaped-number-texts' within Linux/Spyder3 ide 
console, i get funny symbols like a "phone-symbol", triangles or symbols 
for male or female.

>>> print("\7") # gives a phone
>>> print("\5")
>>> print("\1")
>>> print("\21")
>>> print("\30")
>>> print("\31")
>>> print("\32")

def phonesymbol():
	print("\7")

phonesymbol() # prints a phone symbol

my question is, is this a bug or a feature of Spyder3?
if it is a feature, where can I find the complete table of symbols?

within bash - starting python3 - i get some ugly "unicode?" symbols, 
which look like a square containig tiny alphanumeric numbers.

best regards
andy
