Python 2.7. Unicode Errors Simply Explained

I know I'm late with this article for about 5 years or so, but people are still using Python 2.x, so this subject is relevant I think.

Some facts first:

• Unicode is an international encoding standard for use with different languages and scripts
• In python-2.x, there are two types that deal with text.
  1. str is an 8-bit string.

2. unicode is for strings of unicode code points.

target="$1"
remotePath="$2"
device="${3:-/dev/ttyUSB0}"

# compress target files using tar | encode data to base64 string | remove \n
compress="tar -C `dirname $target` -cjvf - `basename $target` | base64 | tr -d '\n'"
# decode base64 string using python (using python because my device doesn't have base64)
base64decode="import base64, sys; sys.stdout.write(base64.b64decode(sys.stdin.read()))"
