I've opened a text-file in Excel.

Some of the cells contain a "weird" character that looks like a square
box. The "weird" character follow the last "normal" character in the
cell. For example, a cell contains "normal" characters like:

MARSALLA LAVON

and the "weird" character follows LAVON


I've posted the cell's contents here but this is what results:

"MARSALLA LAVON "

Since MARSALLA here looks like it's preceded by a double-quote
and LAVON here looks like it's followed by a double-quote, I've
tried replacing the double-quotes with nothing (i.e., "") but Excel
can't find the data I'm searching for.

How do I delete or replace the "weird characters"?
