Of course subject should be VT100 line drawing!

Don't try to play with the page's character encoding. ShellInABox already 
reports the 
correct character encoding to the browser and it makes sure to output 
everything in 
Unicode. If you manually override the character encoding in the browser, it 
either 
doesn't do anything, or really strange things will happen.

ShellInABox understands UTF-8, so the best way to output non-ASCII characters 
is by 
making your application encode them in UTF-8.

But if that is not an option, you can always send the appropriate escape codes 
to 
disable UTF-8 mode and to pick the code page that you want. In your case, that 
would be 
IBM437.

Try running this command prior to running your application:

  echo -ne '\033%@\033(U'

The echo escape sequence works on my CentOS virtual when I cat the mcc.log.

Thank you for the very prompt reply.

I will try the app in the office tomorrow.

We have tried the app tonight using the escape sequences. All OK so far.

How difficult would it be to add the 132 col support including switching back 
and forth?

This is not entirely trivial to do, as most modern browsers don't applications 
to 
arbitrarily resize windows anymore.

And within standard HTML, there also is no easy way to request a font that is 
guaranteed to have a particular dimension.

But when using a WebKit based browser (e.g. Chrome or Safari), we have access 
to CSS 
transforms which allow us to scale arbitrary web content. I believe, on any of 
those 
browsers I could "squish" the font when switching from 80 to 132 column mode. 
It'll 
require a few more changes throughout the code, but I'll see what I can do when 
I 
have a little time to experiment.

Thanks. I am testing using ncurses demos and vttest. I will give a summary in 
the next few days.
