† A byte string is, unsurprisingly, a string of bytes, i.e., char objects. However, unlike a wide string literal, which is always an array of wchar_t objects, a "wide string" in this context is not necessarily a string of wchar_t objects. In fact, the standard never explicitly defines what a "wide string" means, so we're left to guess the meaning from usage.

how does the c++ execution distinguish between the two different type of characters? It doesn't. The compiler decided to encode your string as Unicode at compile-time. In this case, it appears to have chosen UTF-8. How does it know whether its 9 ascii characters or 4 unicode + 1 ascii ?? Again, it doesn't.

How do I index a UNICODE string? It is also worth noting and particularly in C style handling of strings that they use index to traverse or find sub string in a string. This index in ASCII string directly corresponded to the position of item in that string but it has no meaning in a …

Nov 15, 2005 · uses a 16-bit encoding of Unicode code points in characters and string values, a Unicode character in the range U+10000 to U+10FFFF is not permitted in a character literal and is represented using a Unicode surrogate pair in a string literal. Unicode characters with code points above 0x10FFFF are not supported."--

Why does C++ seem to pretend Unicode doesn't exist? Close. 43. Posted by 5 years ago. ... UTF-8 guarantees that there will never be a Nul byte as part of a string, so all of the C/C++ functions that work on Nul terminated strings will be fine. Where it falls down is when you need to work on Characters and not Bytes, because you can have ...

Unicode Character Properties. Each Unicode character, in addition to its value, has certain attributes, or properties. You can match a single character belonging to a particular category with the expression \p{prop}.You can match a single character not belonging to a particular category with the expression \P{prop}.. The three supported property types are scripts, blocks, and a "general" category.

Is it convenient to manipulate Unicode strings in the language? Yes; string methods expect UTF8 strings. How broad/deep does the language support Unicode? What encodings (e.g. UTF-8, UTF-16, etc) can be used? Normalization? Using the standard .NET libraries, there is a …

However, it does break the input into Unicode characters instead of just UTF-16 code units; a surrogate pair is treated as a single character. For example, ଠ (which apparently isn't a valid Unicode character, but appears to have a commonly understood meaning and glyph) is shown as U+20B20. The first column simply displays the character.

This does not actually work because it does not translate UTF-8 outside of string constants, resulting in code that attempts to open files just not compiling. [citation needed] Earlier, and independent of the "UNICODE" switch, Windows also provided the Multibyte Character Sets (MBCS) API switch.
