There are many general skills a programmer should have to be effective and valuable. Some are very general — for instance, the ability to learn and to think abstractly — but some are more specific — various tools and tricks of skilled programming.
Among those tools are several non-programming languages all programmers should know. Those include HTML, XML, SQL, and an old one whose name doesn’t end with “L” — Regular Expressions (aka REs, aka RegEx or RegExp).

Computers process numbers using arithmetic and logic (which amount to the same thing). Processing text, however, requires at least two levels of abstraction. Firstly, a definition of a textual atom — informally a character. Secondly, a definition of a textual unit — typically called a string. A string is an ordered list of characters.
Therein lies a whole field of computer science. From a practical point of view, implementing text has become much easier with Unicode. Different character sets was one of the more awful aspects of dealing with text. (Remember CP-1252?)

The Strings and Text are not the same post on Musing Mortoray discusses the difference between “text” and “strings” and got me thinking. Rather than weigh down his (or her) comment section with a very long comment, I thought I’d go on a bit about it here.
I agree totally with the basic premise: that “text” and “strings” are different beasts. I also agree that text-handling depends on the text. There might be some difference in how we define text and string, and thinking about how I define them turned up a lot of thoughts on the matter. This isn’t intended as an opposition post (except on one point with regard to HTML). What follows is just one programmer’s opinion.
