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).

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?)

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.
