I get that. However then they should name the function and put highly visible disclaimers in the documentation. Something like "from_ascii" instead of "from_chars". Also the documentation, including this blog post should be very clear that this function is only suitable for parsing machine to machine communications and should never be used for human input data. There is clearly a place for this type of function, however this blog post miscommunicates this in a potentially harmful way. When I read the post I presumed that this was a replacement for atoi() even though it had a confusing "non-locale" bullet point.
