ghc7.6.1-darcs-2.8.4-alt2

In the output of some commands Cyrillic letters are not printed as is, but rather as codes, so they are not readable. (Although the locale is Cyrillic.)

$ darcs init
$ echo Здравствуйте > hello.txt
$ darcs add -r .
$ darcs wh 
addfile ./hello.txt
hunk ./hello.txt 1
+<U+00D0><U+0097><U+00D0><U+00B4><U+00D1><U+0080><U+00D0><U+00B0><U+00D0><U+00B2><U+00D1><U+0081><U+00D1><U+0082><U+00D0><U+00B2><U+00D1><U+0083><U+00D0><U+00B9><U+00D1><U+0082><U+00D0><U+00B5>

$ 

As far as I remember, this wasn't like this in some previous version of darcs, probably 2.1.2-alt2 -- http://packages.altlinux.org/en/Platform5/srpms/darcs .

Perhaps, there are other commands where this happens, and I'll report them later.

Workaround: use "darcs diff", which uses the external diff tool (and hence is slower):

$ darcs diff
diff -rN -u old-darcs-Cyr/hello.txt new-darcs-Cyr/hello.txt
--- old-darcs-Cyr/hello.txt	1970-01-01 03:00:00.000000000 +0300
+++ new-darcs-Cyr/hello.txt	2014-05-19 04:11:15.678289159 +0400
@@ -0,0 +1 @@
+Здравствуйте
$ 

From the manpage:

...

           By default, `darcs whatsnew' uses Darcs' internal format for changes.  To see some context (unchanged lines) around  each  change,
           use the --unified option.  To view changes in conventional `diff' format, use the `darcs diff' command; but note that `darcs what‐
           snew' is faster.

...

       darcs diff [file|directory]...
           The  `darcs  diff'  command  compares  two  versions of the working tree of the current repository.  Without options, the pristine
           (recorded) and unrecorded working trees are compared.  This is lower-level than the `darcs whatsnew' command, since it  outputs  a
           line-by-line  diff,  and it is also slower.  As with `darcs whatsnew', if you specify files or directories, changes to other files
           are not listed.  The command always uses an external diff utility.

Also the Cyrillic letters in the output of "darcs whatsnew" generate soem strange garbage around them on dumb terminals:

$ echo world > world.txt
$ darcs add world.txt 
$ darcs wh | cat
addfile ./hello.txt
hunk ./hello.txt 1
+[_<U+00D0>_][_<U+0097>_][_<U+00D0>_][_<U+00B4>_][_<U+00D1>_][_<U+0080>_][_<U+00D0>_][_<U+00B0>_][_<U+00D0>_][_<U+00B2>_][_<U+00D1>_][_<U+0081>_][_<U+00D1>_][_<U+0082>_][_<U+00D0>_][_<U+00B2>_][_<U+00D1>_][_<U+0083>_][_<U+00D0>_][_<U+00B9>_][_<U+00D1>_][_<U+0082>_][_<U+00D0>_][_<U+00B5>_]
addfile ./world.txt
hunk ./world.txt 1
+world
$ 

Perhaps, this are the colored highlighting for these codes (they are printed red)... but this garbage doesn't appear around other highlighted text; for example, above the words "addfile"and"hunk"are printed in blue in a terminal.
