• Purpose of this document
• without being an expert in text and language issues
• Glyphs, graphemes and other Unicode species
• Text operations on encoded strings
• Background
• The facts
• Q: What about Python? I heard they worked hard in v3.3 to support Unicode better.
• How to do text on Windows
• Asian texts: UTF-8 vs. UTF-16
• Further myths on counting characters
• Counting characters can be done in constant time with UTF-16.
• Q: UTF-16 characters that take more than two bytes are extremely rare in the real world. This practically makes UTF-16 a fixed-width encoding, giving it a whole bunch of advantages. Can’t we just neglect these characters?
• Counting characters can be done in constant time with UTF-32.
• should not be important
• In NFC each code point corresponds to one user-perceived character.
• The string
• Our conclusions
• Q: Won’t the conversions between UTF-8 and UTF-16 when passing strings to Windows slow down my application?
• Q: Why not just let any programmer use their favorite encoding internally, as long as they knows how to use it?
• Working with files, filenames and fstreams on Windows
• Conversion functions
• FAQ
• Q: Are you a linuxer? Is this a concealed religious fight against Windows?
• Q: Are you an Anglophile? Do you secretly think English alphabet and culture are superior to any other?
• Q: Why do you guys care? I program in C# and/or Java and I don’t need to care about encodings at all.
• Q: Isn’t UTF-8 merely an attempt to be compatible with ASCII? Why keep this old fossil?
• Q: My application is GUI-only. It does not do IP communications or file IO. Why should I convert strings back and forth all the time for Windows API calls, instead of simply using wide state variables?
• Q: Why do you turn on the
• Q: Isn’t it quite naïve to think that Microsoft will stop using widechars one day?
• Q: What do you think about Byte Order Marks?
• Q: What do you think about line endings?
• Q: But what about performance of text processing algorithms, byte alignment, etc?
• Q: Is it really a fault of UTF-16 that people misuse it, assuming that it is 16 bits per character?
• Q: If
• Q: How do I write UTF-8 string literal in my C++ code?
• Q: I have a complex large char-based Windows application. What is the easiest way to make it Unicode-aware?
• Q: But why
• Q: I already use this approach and I want to make our vision come true. What can I do?
