Hi, in my code I need to "spellcheck" a string in an object to insure a uniform format. I use regexprep for this. One such change needed is to change the greek letters 'α' and 'β' to 'a' and 'b' respectively.
It appears that the command window and actual code handle these letters differently and I need a way to use greek letters in the regexprep.
Code:
classdef myObject < handle
properties
text
end
methods
function obj = myObject(input)
obj.text = input;
spellcheck(obj);
end
function spellcheck(obj)
obj.text = regexprep(obj.text,'β','b');
end
end
end
For example: objText = myObject('testβtest')
returns 'testβtest'
The greek letters in the code are changed to '?' but work fine in the command window.
For example: regexprep('testβtest','β','b')
returns 'testbtest'
Is there a workaround to this problem? It must be relatively efficient, I'm sure opening a file containing the greek letters and assigning them to variables would work but that would slow down the code too much.
Thanks for the help,
~Zach

Maybe it's just me, but I didn't read an actual problem in your question. You say your spellcheck example needs to change beta to b, then go on to show us that it does...

if you type double('β') in the command line it will return 946.
In your code instead of using 'β' use char(946).
