Detailed Description

template<typename NativeIterator>
class u5e::utf8_bounds< NativeIterator >

Check and enforce bounds of utf8 text.

This will only look at the last 6 octets of the text and will only look at the first octet. It will not guarantee that the entire text is valid. The intent of this class is to provide a cheap safety check to make sure you will not have any under or overflow when processing this text.

Template Parameters

NativeIterator

The native type to be iterated over.
