Strings are fixed-length sequences of characters. They can be created by calling constructor procedures, but they can also literally get entered at the REPL or in Scheme source files.
Guile provides a rich set of string processing procedures, because text handling is very important when Guile is used as a scripting language.
Strings always carry the information about how many characters they are
composed of with them, so there is no special end-of-string character,
like in C. That means that Scheme strings can contain any character,
even the NUL character
'\0'. But note: Since most operating
system calls dealing with strings (such as for file operations) expect
strings to be zero-terminated, they might do unexpected things when
called with string containing unusual characters.
