You misread the case here, Theodore.
It's not a problem of language - accented letters and diacritics are used in
many languages and might be used in labels.
Sorry for me just being a stupid downstream user. Such names with «
special » characters in are a flawed design as they have high potential
for confusion ( both for human and system. )
As in your example
foo\$bar → becomes → 'foo\x24bar' → not exactly the same form, which
might not be expected by uneducated user. And ( legitimately ) escaped
but not usable « as is » in all context.
In fact, there's nothing wrong with using any of these characters in
file system labels.
Of course, there's something wrong about using *some* of those characters / \
space * $ #
Accented letters are not the issue ( except with new Ubuntu installer… )
What will be the output of
cd /path/to/{ any label containing / or * or $ or spaces in its name }
if { label name } is not escaped ?
To prevent user from any later confusion, e2label should at least gives
a warning if « special » characters are used inside a label.
And my opinion is that e2label should strictly prevent using those « special »
characters inside label.
While those can be « managed » with escaping, « names » in paths should never
create confusion, so avoiding by default / or $ or * sound safer to me.

Title:
won't warn neither prevent usage of « risky » characters in labels
Status in e2fsprogs package in Ubuntu:
Confirmed
Bug description:
Hi,
if naming or renaming an EXT volume,
e2label lets you use any character, including / or * or $ ( and
probably others, like accented letters é è à )
I'd expect at least a warning if such are to be found in a label name.
Or better, it should not be possible to use those in label names.
Example :
a@p:~$ sudo e2label /dev/sdb12 /Ti\$*
a@p:~$
a@p:~$ sudo e2label /dev/sdb12
/Ti$*
a@p:~$
a@p:~$ lsblk -fe7 | grep sdb12
└─sdb12 ext4 1.0 /Ti$*
