While fixing some PHPCS issues, I found something strange here [1] (you need to get the last master version).

As you can see, there is a mb_strpos !== true… but, this should always be true… mb_strpos can't be strictly true, it could be false are an int.

It seems that this condition is here since the file is created (commit 7248bf87fad6f371943c7b26c3a597bc04265dc7 – from the log, I can imagine that the code wasn't in a class before).

Did anyone already use this import please? Because I can't believe that the returned value is not the initial $cell…

Thanks for your feedbacks,

Hugues.
