Problem with shortened uploaded files

[t-szczyrba]

Hi,
I've noticed some strange behaviour: the files I upload over webdav are finally shortened by a couple of bytes.

In workstation ( where I edit the file):
$ ls -lR
.:
total 20
-rw-rw-r-- 1 trevor trevor 137 Sep 17 14:46 README.txt
drwxrwxr-x 2 trevor trevor 4096 Sep 18 12:35 files
-rw-rw-r-- 1 trevor trevor 393 Sep 18 12:43 package.json
drwxrwxr-x 2 trevor trevor 4096 Sep 17 15:12 srv
-rw-rw-r-- 1 trevor trevor 64 Sep 18 12:38 webdav.json

./files:
total 4
-rw-rw-r-- 1 trevor trevor 350 Sep 18 12:54 404.html

./srv:
total 4
-rw-rw-r-- 1 trevor trevor 2818 Sep 18 12:54 index.js

In server ( where I upload the file):
$ls -lR
.:
total 24
-rw-r--r-- 1 www-data www-data 132 Sep 18 13:05 README.txt
drwxr-xr-x 2 www-data www-data 4096 Sep 18 12:55 files
-rw-r--r-- 1 www-data www-data 388 Sep 18 12:43 package.json
drwxr-xr-x 2 www-data www-data 4096 Sep 18 12:54 srv
-rw-r--r-- 1 www-data www-data 64 Sep 18 12:40 webdav.json

./files:
total 4
-rw-r--r-- 1 www-data www-data 346 Sep 18 12:55 404.html

./srv:
total 4
-rw-r--r-- 1 www-data www-data 2812 Sep 18 12:54 index.js

apache2 version 2.4.18-2ubuntu3.9

I have confirmed that the size difference happens in files utf8 encoded with some characters.
When in the file are no multibyte characters everything is fine, but it they are some ( ie: 'ą' character ) the size difference appears,
