Hi folks,

I read this: [http://ruby-gnome2.sourceforge.jp/hiki.cgi?pango-markup](http://ruby-gnome2.sourceforge.jp/hiki.cgi?pango-markup)

And I ran the following snippet on Windows 7.

# I’m using Ruby 1.9.3p0. The gtk2, cairo and pango are all 1.0.3.

require ‘cairo’  
require ‘pango’  
require ‘gtk2’  
win = Gtk::Window.new  
surface = Cairo::ImageSurface.new Cairo::FORMAT\_ARGB32, 300, 300  
context = Cairo::Context.new surface  
layout = context.create\_pango\_layout  
markup = “small-CAPS\nSMALL-CAPS”  
attr\_list, text = Pango.parse\_markup(markup)  
layout.text = text  
layout.attributes = attr\_list  
context.show\_pango\_layout layout  
context.show\_page  
surface.write\_to\_png ‘hello.png’  
img = Gtk::Image.new ‘hello.png’  
canvas = Gtk::Layout.new  
canvas.put img, 0, 0  
win.add canvas  
win.show\_all  
Gtk.main

I expected that it’d show the same two 'SMALL-CAPS’s.  
But I got this: [http://www.rin-shun.com/tmp/smallcaps.png](http://www.rin-shun.com/tmp/smallcaps.png)

The variant attribute seems not to work well…  
Please correct me if I’m wrong.

I looked at Pango’s source code and noticed that Pango  
doesn’t implement variant… Pango just accepts ‘normal’ or  
‘smallcaps’. So you can’t use variant in Pango markup.

## Thanks,

Hi Kou,

Thank you so much for taking your time to figure out the problem.  
Okay, I’m looking forward to see Pango’s update in the future. 🙂
