+ <p>Sets the range of characters that the system will consider printable in heuristic detection of strings. This typically affects the shell, debugger and io:format functions (when ~tp is used in the format string).</p>
+ <p>Currently two values for the <c>Range</c> are supported:
+ <taglist>
+ <tag><c>latin1</c></tag> <item>The default. Only characters
+ in the ISO-latin-1 range can be considered printable, which means
+ that a character with a code point &gt; 255 will never be
+ considered printable and that lists containing such
+ characters will be displayed as lists of integers rather
+ than text strings by tools.</item>
+ <tag><c>unicode</c></tag>
+ <item>All printable Unicode characters are considered when
+ determining if a list of integers is to be displayed in
+ string syntax. This may give unexpected results if for
+ example your font does not cover all Unicode
+ characters.</item>
