[Expo-tech] !DOCTYPE & charset=

Fri Dec 20 18:01:35 GMT 2019

More fund with grep.

Since it’s 9 years since HTML5 and CSS3 came out, I think we can agree that they are stable enough now for Expo use, so long as we are careful not to be too bold with them.

$ cd expoweb

$ grep -ahr DOCTYPE * | sort | uniq -c | sort -n

      1 <!DOCTYPE html>

      1 <!DOCTYPE HTML>

      1 <!DOCTYPE html PUBLIC "-//IETF//DTD HTML 4.0//EN">

    921 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>

tidying up ISO-8859-1 & UTF-8 will mostly be a matter of handling umlauts I imagine.

The site is split pretty evenly between the two it seems.

I *presume* that we should standardise on UTF-8 but I’m all ears for alternative suggestions. (I see we have a “utf8” crept in there).

Similarly I would assume that standardising on <!DOCTYPE HTML> is uncontentious ?

I do enjoy a bit of software archaeology. (Does anyone else here follow  <https://twitter.com/arclight> @arclight ?)
