samba - Dec 2019 - Mac clients trouble with NFD accented characters on Samba share

File names on a Samba share with accented characters using the NFD form 
of UTF8 cannot be seen or used by Mac clients.

While tying to find a solution, I came across this old thread : 
https://lists.samba.org/archive/samba/2014-December/187545.html 
("[Samba] Mount unix samba 4 share to osx client without mangled file 
names")

A reply in that thread suggested:

So I enabled vfs_fruit, but it doesn't seem to help for accented 
characters. Maybe it only solves a problem with illegal characters?

This is what I tried, but which didn't help:

Create the folders/files on the Samba server (Debian 9, smbd version 
4.5.16) :

    mkdir v?los_1                     # normal NFC dir
    mkdir "ve$(printf '\u301')los_2"  # NFD dir

    cd v*_1
    echo "NFC" >> v?lo.txt

    cd ../v*_2
    echo "NFD" >> "ve$(printf '\u301')lo.txt"

This is my samba config:

    # testparm -s
    Load smb config files from /etc/samba/smb.conf
    rlimit_max: increasing rlimit_max (1024) to minimum Windows limit
    (16384)
    Processing section "[homes]"
    Processing section "[share]"
    Processing section "[temp]"
    Loaded services file OK.

     ??? comment = on /home for tests, temp etc.
     ??? path = /home/temp
     ??? force user = alma
     ??? guest ok = Yes
     ??? read only = No


I could set up a cron job to rename all the problem files and folders 
every night using convmv.

But before doing that, I would like to make sure I'm not overlooking a 
simpler solution through the Samba configuration.

Thanks for any help,

MI

yes, Samba expects NFC. Use convmv to fix your filenames.
