Introduction to Unicode: The Problem
? Storing scripts: human readable text data
每 Localization (l10n) and Internationalization (i18n) of software and

每 Basis for national language and script support
每 Common ground for textual information

Python & Unicode
Introduction to Unicode: First Approximations
? Mappings of bytes to characters: Code Pages (CP)
每 Problem: Attaching the encoding information to the data
No support in the OS for maintaining per data buffer encoding information
Each application/protocol has to implement its own way of dealing with encodings
每 Problem: Scripts with many characters
e.g. Asian scripts use shift information to address all characters using 8 bits
每 Problem: Not available for ancient scripts
e.g. Old Italic
每 Problem: Incompatible mappings for the same script
e.g. Latin-1 and Windows CP-152x
