I want to read an Excel file giving me names and units of some data. There is quite a lot of units with "°" (symbol for degree) in the table and I don't get them read correctly using xlsread. If I use the 2nd return parameter of xlsread, I get '' instead of '°'. If I use the 3rd return parameter, I get  instead of '°'.
Is there any way to get this unit read correctly into a MATLAB string?
I have to use MATLAB R2010b.
