Re: ACS/UTF-8 Line Drawing Question

[Marc Smith]

Hi,

I'm following up on this to see if you had any additional advice --
I'd really like to make PuTTY work out-of-the-box. Currently, users of
my software must change the remote character set to "Latin-1, West
Europe" when using PuTTY in order for the line drawing characters to
display properly. No other terminal emulators that I've come across
have this issue.

My TUI application is using the CDK library. Does
"NCURSES_NO_UTF8_ACS=1" not affect this? I believe CDK uses everything
via ncurses, but maybe something related to the line drawing is
implemented differently? I'm out of ideas, so any help would be
greatly appreciated.

Thanks for your time.
