eval fails with load when path or filename has space(s)

If I run
load [dirpath filename]
and dirpath or filename has a space, it loads the file just fine. But if I use
eval(['load ' [dirpath filename]]);
Matlab prints "Unable to read file .... No such file or directory".
I noticed that if I type
dir C:\mydir\
then tab, the path is printed with a ' whereever there is a space. But I'm not sure how to mimic that. Are spaces in path or filename in this instance a limitation of Matlab, or is there a solution?

Like we always say: don't use eval()
Question: are you sure you are using
load [dirpath filename]
and not
load( [dirpath filename] )
??
Also, have you considered using fullfile() ?

There is a difference in the way functions handle strings when they are called with the function form (with parentheses) vs. the command line form (no parentheses). Walter would be better than me at explaining why. Anyway, you can use sprintf() and three or 4 ' to write a ' into a string.
