Ha, ha!
What do you mean exactly, convert them into the "standard" output? What form do
you expect, and to do what?
Maybe your aim is to replace number-coded html entities in a python string by
real characters in a given format, to be able to output them. Then one way may
be to use a simple regex and replace with a custom function. Eg:
import re
def rep(result):
string = result.group() # "&#xxx;"
n = int(string[2:-1])
uchar = unichr(n) # matching unicode char
# for you dest format may be iso-8859-2 ?
return unicode.encode(uchar, "utf-8") # format-encoded char
source = "xxx¡xxxÂxxxÿxxx"
pat = re.compile("""&#\d+;""")
print pat.sub(rep, source)
