Re: OS X and umlauts in file names

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I've did following:

 toms-mac-mini:git-umlauts tom$ ls
 Überlänge.txt
 toms-mac-mini:git-umlauts tom$ git status
 # On branch master
 #
 # Initial commit
 #
 # Changes to be committed:
 #   (use "git rm --cached <file>..." to unstage)
 #
  #	new file:   "U\314\210berla\314\210nge.txt"
 #
 toms-mac-mini:git-umlauts tom$ git stage "U\314\210berla\314\210nge.txt"
 fatal: pathspec 'U\314\210berla\314\210nge.txt' did not match any files

Note, that I copy-pasted the file name which 'git status' showed to the
stage command. IMHO, this should work, especially, because different people
said Git would treat the file name as byte-array without interpreting it in
some kind.

>From the user with the German OS X (for which the staging is said to work),
I've got the output of 'env' and hence also tried

 export LANG=de_DE.UTF-8

before doing the above steps, but with the same results. :(
