Single characters (without trailing line break) won't get recognized/displayed by clipcat

[LnLcFlx]

When I do

echo 'a' | xclip -selection clipboard

a\n gets shown by clipcatctl list but when removing the trailing line break

echo -n 'a' | xclip -selection clipboard

or

echo 'a' | xclip -rmlastnl -selection clipboard

it does not while xclip -out -selection clipboard does show a (a%).

Same problem when doing Ctrl-C on single characters in a browser for example.
Notice that this has nothing to do with the line break character itself but rather that there is no second character:
For example

echo -n 'aa' | xclip -selection clipboard

works again.

Turns out this is due to the default filter_text_min_length = 1 in clipcatd.toml.
Setting this to 0 fixes it.
