garbled entries to directory hotlist

[ctmp1]

mc adds garbled entries to directory hotlist

Steps to reproduce:

1. run mc
2. press ctrl-\ to show directory hotlist dialog
3. press 'add current'
4. change proposed name in dialog box (this is not strictly necessary but sometimes the error doesn't show without this) and press enter
5. try to use the new entry

• you will get something like this

Cannot chdir to "?\7.e/lg/.config/mc/hotlist.bak"
No such file or directory (2)

6. close mc

The hotlist file in ~/.config/mc now contains this

---
ENTRY "/home/lg/.MestreLa? b" URL "�
7<>e/lg/.config/mc/hotlist.bak"
---

This entry was produced when i bookmarked /home/lg/.MestreLab? directory

Sometimes when i close mc after using this broken directory hotlist i get something like this:
