C Builder Unicodestring Compare. Standard strings, unicode, ucs4string, utf8, utf16, ascii, wide wstring, ansistring, codepages. When comparing two strings, the compiler sometimes checks lowercase and.
Comparing unicode strings containing combining characters. Compare () is a public member function of string class. A bstr is a unicode string that has its length prepended, and is also terminated by a zero character.
Now, during runtime, delphi correctly displays that unicode string (which is serbian cyrillic), but c++ builder not. This method takes one argument as a wide c. But there should be no other choice, and we.
Suppose to have a unicode character that is a precomposed character, i.e. It should be possible to define. You need to normalize the strings using a library like icu to compare them correctly, or at least with your example, type the combining character the same way in both string.
Icu provides a small number of functions that allow any unicode characters to be. Two basic concepts are stressed here. Bytes provides a very readable overview of unicode encodings.
String comparison allows you to find out which one of two strings is longer or whether both strings are equal. We would still have to allow to disable renaming, that is, sometimes the icu namespace is icu_4_2 (with an alias of icu) and sometimes it's just icu. Size_t is defined as an unsigned integral.
Hardcoding a unicode string is mostly a matter of deciding how you want to enter the string in your source editor. A bstr is a unicode string that has its length prepended, and is also terminated by a zero character. The good news is that if you use wchar_t* strings and the family of functions.
