-	# - It returns the empty string when LANG is set to a locale of the
-	#   form ll_CC, although ll_CC/LC_CTYPE is a symlink to an UTF-8
-	#   LC_CTYPE file.
-	# - The environment variables LANG, LC_CTYPE, LC_ALL are not set by
-	#   the system; nl_langinfo(CODESET) returns "US-ASCII" in this case.
-	# - The documentation says:
-	#     "... all code that calls BSD system routines should ensure
-	#      that the const *char parameters of these routines are in UTF-8
-	#      encoding. All BSD system functions expect their string
-	#      parameters to be in UTF-8 encoding and nothing else."
-	#   It also says
-	#     "An additional caveat is that string parameters for files,
-	#      paths, and other file-system entities must be in canonical
-	#      UTF-8. In a canonical UTF-8 Unicode string, all decomposable
-	#      characters are decomposed ..."
-	#   but this is not true: You can pass non-decomposed UTF-8 strings
-	#   to file system functions, and it is the OS which will convert
-	#   them to decomposed UTF-8 before accessing the file system.
-	# - The Apple Terminal application displays UTF-8 by default.
-	# - However, other applications are free to use different encodings:
-	#   - xterm uses ISO-8859-1 by default.
-	#   - TextEdit uses MacRoman by default.
-	# We prefer UTF-8 over decomposed UTF-8-MAC because one should
-	# minimize the use of decomposed Unicode. Unfortunately, through the
-	# Darwin file system, decomposed UTF-8 strings are leaked into user
-	# space nevertheless.
-	# Then there are also the locales with encodings other than US-ASCII
-	# and UTF-8. These locales can be occasionally useful to users (e.g.
-	# when grepping through ISO-8859-1 encoded text files), when all their
-	# file names are in US-ASCII.

+    #   form ll_CC, although ll_CC/LC_CTYPE is a symlink to an UTF-8
+    #   LC_CTYPE file.
+    # - The environment variables LANG, LC_CTYPE, LC_ALL are not set by
+    #   the system; nl_langinfo(CODESET) returns "US-ASCII" in this case.
+    # - The documentation says:
+    #     "... all code that calls BSD system routines should ensure
+    #      that the const *char parameters of these routines are in UTF-8
+    #      encoding. All BSD system functions expect their string
+    #      parameters to be in UTF-8 encoding and nothing else."
+    #   It also says
+    #     "An additional caveat is that string parameters for files,
+    #      paths, and other file-system entities must be in canonical
+    #      UTF-8. In a canonical UTF-8 Unicode string, all decomposable
+    #      characters are decomposed ..."
+    #   but this is not true: You can pass non-decomposed UTF-8 strings
+    #   to file system functions, and it is the OS which will convert
+    #   them to decomposed UTF-8 before accessing the file system.
+    # - The Apple Terminal application displays UTF-8 by default.
+    # - However, other applications are free to use different encodings:
+    #   - xterm uses ISO-8859-1 by default.
+    #   - TextEdit uses MacRoman by default.
+    # We prefer UTF-8 over decomposed UTF-8-MAC because one should
+    # minimize the use of decomposed Unicode. Unfortunately, through the
+    # Darwin file system, decomposed UTF-8 strings are leaked into user
+    # space nevertheless.
+    # Then there are also the locales with encodings other than US-ASCII
+    # and UTF-8. These locales can be occasionally useful to users (e.g.
+    # when grepping through ISO-8859-1 encoded text files), when all their
