This is initialized with reasonable defaults for most types. How do I display the latest Unicode characters (esp. 0 (and backported to Python 2. Examples are EBCDIC and Macintosh code pages. # In Python, print red text using ANSI escape codes # Doesn't work well in Windows though print('\033[2J') # Clear screen. All codecs including unicode-escape only dealt with byte conversion; (unicode-escape converts everything to printable 7bit ascii); these patches want to add a feature related to the "where does the string end" issue, and is only aimed at "python code" containers. It is quite likely that when migrating existing code and writing new code you may be unaware of this change as most string algorithms will work with either type of representation; but you cannot intermix the two. Any Unicode character can be encoded this way, but characters outside the Basic Multilingual Plane (BMP) will be encoded using a surrogate pair if Python is compiled to use 16-bit code units (the default).
