unicode(ucs-2,ucs-4,utf8,utf16,utf32)

https://blog.csdn.net/left_la/article/details/36188181

  • UCS-2(niversal Character Set coded in 2 octets)
  • UCS-4(Universal Character Set coded in 4 octets)
  • UTF-16(16-bit Unicode Transformation Format)
  • UTF-8 is a variable-width character encoding
  • BOM(Byte Order Mark) 字节序标志

charset in c++

sizeof(wchar_t)=16 for windows sizeof(wchar_t)=32 for linux and mac so better use char16_t for utf16 and char32 for unicode

gcc and glibc version map

clang use gcc sysroot for compile and crosscompile

this is clang print for gcc version usage and include header search path [clang|gcc] -E -xc++ -v - < /dev/null with right --sysroot path can let clang work properties

some gcc toolchain dir strcuture not suitable for directly use for clang need define --sysroot=/path/to/mips-gcc472-glibc216-64bit/mips-linux-gnu/libc and (cd mips-gcc472-glibc216-64bit/mips-linux-gnu/libc/lib/ && ln -s gcc ../../../lib/gcc) to adjust dir for clang make full use of this gcc toolchain, ref detail for:https://stackoverflow.com/questions/41962611/how-to-select-a-particular-gcc-toolchain-in-clang
