@Mon9oose, the strdisplaywidth() was added to vim 7.3, and the and() function was added to vim 7.4. Is there a way you can upgrade to a newer version of Vim? I will look for a backward compatible alternative, but a Vim upgrade could be quicker.

@PhilRunninger, thx your opinion. this server using many other server engineers. (Dev server) I will share this issue, and propose an upgrade vim :-)

I'm reopening this to make sure I give it the attention it needs.

PhilRunninger commented 5 years ago

I wasn't able to figure out an alternative for strdisplaywidth(), so I upped the minimum required version of vim to 7.3.
