Plesk on Ubuntu 16.04: 'error while loading shared libraries: libicuuc.so'

Just had this weird issue installing Plesk on a new Ubuntu 16.04 server:

error while loading shared libraries: libicuuc.so.55

(I imagine the number at the end may change according to whichever version of the library it's trying to load.)

I solved it by running:

sudo apt install libicu55

Apparently the missing file is a Unicode library, presumably used for Plesk's internationalisation. Totally safe to install.
