+.Sh NAME
+.Nm Str
+.Nd Functions for manipulating and creating strings.
+.Sh SYNOPSIS
+.In Str.h
+.Ft char *
+.Fn StrUtf8Encode "unsigned long"
+.Ft char *
+.Fn StrDuplicate "const char *"
+.Ft char *
+.Fn StrConcat "size_t" "..."
+.Ft char *
+.Fn StrRandom "size_t"
+.Sh DESCRIPTION
+.Nm
+provides string-related functions. It is called
+.Nm ,
+not String, because some platforms (Windows) do not have
+case-sensitive filesystems, so String and string are the same thing, which poses
+a problem because string is a standard library header.
+.Pp
+.Fn StrUtf8Encode
+takes a UTF-8 codepoint and encodes it into a string buffer containing between
+1 and 4 bytes. The string buffer is allocated on the heap, so it should be freed
+when it is no longer needed.
+.Pp
+.Fn StrDuplicate
+duplicates a NULL-terminated string, and returns a new string on the heap. This is
+useful when a function takes in a string that it needs to store for long amounts
+of time, even perhaps after the original string is gone.
+.Pp
+.Fn StrConcat
+is a var-args function that takes the number of NULL-terminated strings specified
+by the first argument, and returns a new string that contains their concatenation.
+It works a lot like
+.Xr strcat 3 ,
+but it takes care of allocating memory big enough to hold all the strings. Any
+strings may be NULL. If a string is NULL, it is treated like an empty string.
+.Pp
+.Fn StrRandom
+generates a random string of the specified length.
