+This is a sample of Tk's support for languages that use non-Western \
+character sets. However, what you will actually see below depends \
+largely on what character sets you have installed, and what you see \
+for characters that are not present varies greatly between platforms as well. \
+Please try to click the 'See Code' button, \
+and click the 'Rerun Demo' button after editing \
+(the source file is not changed) \
+the definition of @@font on the Unicodeout_SampleFrame class.
+The strings are written in Tcl using UNICODE characters \
+using the \\uXXXX escape so as to do so in a portable fashion.
+
+ATTENTION:
+The strings are converted to the encoded string objects \
+(completed to rewrite Tcl's escapes) by Tk::UTF8_String method. \
+And the Tk::UTF8_String objects are passed to the label widgets.
