-Because the text encoding problem on Windows, here I write some functions
-related to text encoding. The utf-8 and utf-16 conversion function is provided
-by win32 api. However win32 api does not provide any function about charactor
-iteration or index by code point. (At least I haven't found.) I don't use icu
-because it is not easy to build it on Windows and the bundled version in Windows
-(https://docs.microsoft.com/en-us/windows/win32/intl/international-components-for-unicode--icu-)
-is only available after Windows 10 Creators Update.
-
-Luckily, both utf-8 and utf-16 encoding are easy to learn and program with if we
-only do simple iteration rather than do much sophisticated work about
-complicated error situations. (And I learn the internal of the encoding by the
-way.)
