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.
