Detailed Description

template<typename Type>
class NCollection_UtfString< Type >

This template class represent constant UTF-* string. String stored in memory continuously, always NULL-terminated and can be used as standard C-string using ToCString() method.

Notice that changing the string is not allowed and any modifications should produce new string.

In comments to this class, terms "Unicode symbol" is used as synonym of "Unicode code point".
