Something strange has started happening recently. For a long time I have
used ISO-8859-1 as my character mapping in text consoles.
dpkg-reconfigure console-setup
and I have had no difficulty, except when using the ssh client to connect
to a remote system which uses UTF-8. The box-drawing characters sent by
the remote system did not look right under these conditions. To solve this
problem, I switched my local system to use UTF-8. Now the box-drawing
characters sent by the remote system look right when displayed by my
local ssh client. However, I recently began noticing that all blue fields
are now overlined. For example, the lynx web browser, when used in a
text console (vt1-vt6), displays emphasized fields (the <em>...</em> html
tag) as blue overlined, when it used to display them simply as blue.
I can live with that, I suppose. But what really bothers me is when I
use the c3270 text-mode 3270 terminal emulator to logon to a mainframe.
All blue fields are now overlined! This is driving me batty! I tried
searching the world wide web using search words of
blue overlining "UTF-8"
but did not obtain any useful results. Does anyone know the cause of this?
Does anyone know the cure? Is this a bug? If so, in what package is the
bug? The problem does not seem to occur in a Gnome Terminal window, only
on a text console. My system locale is en_US.UTF-8. I am running an
up-to-date Jessie system on i386 architecture.
