Detailed Description

Non-owning view over a range of characters with UTF Encoding.

It additional also holds the SC::StringEncoding information (ASCII, UTF8 or UTF16). During construction the encoding information and the null-termination state must be specified. All methods are const because it's not possible to modify a string with it.
Example (Construct)

StringView s("asd");
SC_ASSERT_RELEASE(s.sizeInBytes() == 3);
SC_ASSERT_RELEASE(s.isNullTerminated());

Example (Construct from null terminated string)

const char* someString = "asdf";
// construct only "asd", not null terminated (as there is 'f' after 'd')
StringView s({someString, strlen(asd) - 1}, false, StringEncoding::Ascii);
SC_ASSERT_RELEASE(s.sizeInBytes() == 3);
SC_ASSERT_RELEASE(not s.isNullTerminated());
//
// ... or
StringView s2 = StringView::fromNullTerminated(s, StringEncoding::Ascii); // s2 == "asdf"
