Subject:	d --tree problem with "line draw" characters
Date:	Tue, 18 Nov 2003 09:38:28 -0500
MIME-Version:	1.0

d -t in bash in a command shell gives string like "0xB", "0mqB", "0tqB",
etc, instead of line draw characters or ASCII characters that can substitute
for line draw characters (e.g., "|-\+").

for example
/c/dw2> d -t -c- | head
/c/DW2/:
  0tqBNIAID/:
  0xB   0mqBNIAID.batch
  0tqBout/:
  0xB   0tqBCC/:
  0xB   0tqBCDC/:
  0xB   0tqBCIT/:
  0xB   0tqBFDA/:
  0xB   0tqBFIC/:
  0xB   0tqBIHS/:
/c/dw2> d -t -c- | head | od -c

What environmental variable need to be set to get to get this to work?

Might the maintainer patch d so that it detects the state and automatically
puts out the characters that work?  (I know, PTC, but I'm not a programmer.)

For the record, one can do the following (note the reintroduction of
colorization), but it is a severely inconvenient:
/c/dw2> d -t | head | sed -e 's/^[(B//g' -e 's/^[(0x/|/g' -e 's/^[(0tq/+/g'
-e 's/^[(0mq/\\/g'
/c/DW2/:
  +NIAID/:
  |   \NIAID.batch
  +out/:
  |   +CC/:
  |   +CDC/:
  |   +CIT/:
  |   +FDA/:
  |   +FIC/:
  |   +IHS/:
