+/// Creates a new `StringView` without checking if the indices are valid UTF-16
+/// boundaries.
+///
+/// Parameters:
+///
+/// * `string` : The source string to create a view from.
+/// * `start` : The starting UTF-16 code unit index into the string.
+/// * `end` : The ending UTF-16 code unit index into the string (exclusive).
+///
+/// Returns a new `StringView` instance that provides a view into the specified
+/// portion of the string.
+///
+/// Example:
+///
+/// ```moonbit
+/// test "StringView::unsafe_make" {
+///   let str = "Hello🌍"
+///   let view = StringView::unsafe_make(str, 0, 5)
+///   inspect!(view, content="Hello")
+/// }
+/// ```

+/// @alert unsafe "This function does not check if the indices are valid UTF-16 boundaries. Use String::op_as\_view for safe string view creation."
