This content is 20 years old. I don't routinely update old blog posts as they are only intended to represent a view at a particular point in time. Please be warned that the information here may be out of date.
I use Blogger to create and update this blog (because it’s quick and easy, whilst still giving me a level of control over layout etc.).
Unfortunately, the graphical interface in Blogger strips out some non-alphanumeric characters, such as the pipe symbol (|) meaning that a little bit of HTML massage is needed from time to time.
Whilst editing such a post today I came across a collection of useful tables for ASCII codes, HTML codes, control codes and conversion.
