%TESTNCTEXT  NetCDF text attribute test.
%
%  Input and output of text attributes to NetCDF files is not consistent when
%  they contain non-ASCII characters. Saving the attribute to a file and loading
%  it again doest not recover the original value.
%
%  The cause of the problem seems to be the different data types used by MATLAB 
%  and NetCDF to represent character data, and that it is not documented how 
%  the conversion is done:
