Custom char not working about micropython-i2c-lcd

[expert-m]

I have created PR with a fix that works for me.

Hi @dobova86, seems to be valid. I can kind of fix the issue by calling lcd.print(chr(0)) twice. Maybe needs some more investigations. Could also be a timing issue as it does not happen when I call the function in the repl

I've been able to print custom char sending lcd.set_cursor(col=0, row=0) before print.
May be some memory state need to be reset before lcd.print( chr(x)).

Came here to report the same. I can confirm that the PR works as expected.
