unicode character lookup

From ASCII code to Unicode Double-byte Character setSo far, we've seen a 256 character character set (ASCII). But there are about 21,000 glyphs in China, Japan and South Korea. How to accommodate these languages and still maintain some compatibility with ASCII?The solution (if this is correct) is a double-byte

Summary of Unicode, ANSI character set, and related string operationsQ How to display Unicode stringsAIf the program defines _ Unicode macro, directly useWchar * STR = l "unicodestring ";Textout (0, 0, STR );Otherwise, the conversion type is required.# Include Wchar * STR = l "unicodestring ";Bstr_t str1 = STR;Textout

lpuseddefachar char must be null when this value is setCp_utf8 UTF-8, which must be null for both lpdefaultchar and lpuseddefachar char I think cp_acp and cp_utf8 are the most common ones. The former converts wide characters to ANSI and the latter to utf8. Dwflags: Specifies how to process non-converted characters. However, if this parameter is not set, the function runs faster. I set it to 0. The following table lists the configurable values:Wc_no_best_fit_chars converts

Character encoding: ASCII, Unicode, UTF-8, gb2312 1. ASCII code We know that in a computer, all information is eventually represented as a binary string. Each binary bit has two states: 0 and 1. Therefore, eight binary bits can combine 256 states, which is called a byte ). That is to say, a single byte can be used to represent 256 different States. Each State corresponds to one symbol, that is, 256 symbol

For example, the SPACE is 32 (Binary 00100000), and the uppercase letter A is 65 (Binary 01000001 ). These 128 symbols (including 32 control symbols that cannot be printed) only occupy the last seven digits of one byte, and the first
