+In Nim, <code>len</code> returns the byte length of strings, ignoring the UTF-8 encoding. When dealing with Unicode strings, the module <code>unicode</code> must be used.
-===Byte Length===
-<lang Nim>var s: string = "Hello, world! ☺"
+<lang Nim>import strformat, unicode
-echo '"',s, '"'," has byte length: ", len(s)
-# ->  "Hello, world! ☺" has unicode char length: 17</lang>
+var s: string = "Hello, world! ☺"
+echo &"“{s}” has byte length {s.len}."
-===Character Length===
+echo &"“{s}” has Unicode char length {s.runeLen}."</lang>
-<lang Nim>import unicode
-var s: string = "Hello, world! ☺"
-echo '"',s, '"'," has unicode char length: ", runeLen(s)
+{{out}}
-# ->  "Hello, world! ☺" has unicode char length: 15</lang>
+<pre>“Hello, world! ☺” has byte length 17.
+“Hello, world! ☺” has Unicode char length 15.</len>
