Cygwin Mintty unicode doesn't display fail despite having dejavu sans mono and everything

Question

Edit

the problem is ubuntu machine can't display \u03bb as greek lambda symbol

ubuntu is remote:

[ubuntu@ubuntu:~]$echo -e "\xce\xbb\x0a" 
λ 

[ubuntu@ubuntu:~]$echo -e "\u03bb" 
\u03BB 

this is local:

matizmabel@Casper ~ 
$ echo -e "\u03bb" 
λ 

matizmabel@Casper ~ 
$ echo -e "\xce\xbb" 
λ 

matizmabel@Casper ~ 
$

I use cygwin mintty terminal.

I use Dejavu Sans Mono and this:

$ locale
LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_ALL=

I ssh into ubuntu headless server, and have this issue. Please fix my unicode display problem.

Answer 1

See http://www.utf8-chartable.de/unicode-utf8-table.pl

Unicode code point = U+039B

character = Λ

UTF-8 (hex.) = ce 9b

 $ echo -e "\xCE\x9B"

 Λ

If the problem is remote only, likely that "echo" don't undeerstand the "\u039B" escape. Please note that "\u" is not reported as escape sequence in echo coreutils manuals. nor in POSIX

http://pubs.opengroup.org/onlinepubs/9699919799/utilities/echo.html

To check it

$ echo -ne "\xce\xbb" |od -x
0000000 bbce
0000002


$  echo -ne "\u03bb" |od -x
0000000 bbce
0000002
