open() build-in function don't work as expected #706
Description
Hello,
first of all sorry for my bad english, i do not use it often.
Said that, i found the following two possible bugs:
The first concerns the carriage return that on Android is recognizes only the LF and then when meets the other 2 types it give trouble.
So in practice, if you want to create a file directly from Android or on a Linux machine should be no problem, but when you create the file with an OS that uses another kind of carriage return and then transferred to Android system then you will have that problem.
The second problem concerns the special characters as, for example, the "copyright" © which returns the following error traceback:

This problem may be related to this type of implementation of the code http://stackoverflow.com/a/5245904, but in this case the workarounds proposed do not solve (at least in my opinion) the compatibily problems.
Both of the above problems occur only in the Android platform, which instead in others Python implementation that i have tested (windows/linux) are all easily managed.
I used buildozer toolkit to build the following test code:
main.py
from kivy.app import App
from kivy.uix.button import Button
from opentest import *
#filepath = "/home/valerio/PROGETTI/opentest/page.html" #test in xubuntu
filepath = "/data/data/opentest.test.opentest/files/page.html" #test in android 4.4.2
#filepath = "C:\Users\valerio\Desktop\open\testpage.html" #test in windows vista
class mainApp(App):
def build(self):
open_test(filepath)
return Button(text='Hello World')
mainApp().run()
opentest.py
def open_test(filepath):
fli = ""
print filepath
print "-----"
with open(filepath,"rb") as file:
# print file.read()
fli = file.read()
# for f in file:
# fli += f
# while True:
# lin = file.readline()
# if lin != "":
# fli += lin
# else:
# break
# print open(filepath,"rb").read()
print fli
print "-----"

<!-- This file is needed for test the Android platform -->
<html><head><title>test title</title></head><body>test body<div>©test div</div>

It would be great if you could solve it in the upcoming milestone or at least in the dev branch.
thanks
