How to be able to read file names with Swedish characters (ÅÄÖ) from a zipped file? Also how to unzip the files to a folder with the same name as the zipped folder?

Hi

I have two quesions:

I am trying to unzip a folder which includes list text files with names containing Swedish characters like (Å,Ä,Ö, å, ä, ö). When using the function unzip, the Swedish characters with unzipped files are switched with � instead. For example when teh writing the following matlab code:

unzip('C:\Desktop\zipData\2019-06-10.zip','C:\Desktop\unzipData')

For example, the unzipped text file name in the folder C:\Desktop\unzipData would be Plant4_�A01_GT01 instead of Plant4_ÅA01_GT01.

I tried to change the encoding as below but it also did not work:

slCharacterEncoding('UTF-8')

Q1: is there a way fix the above mentioned issue?

Additionally, when using the function unzip('C:\Desktop\zipData\2019-06-10.zip','C:\Desktop\unzipData'), the function extract all the text files from 'C:\Desktop\zipData\2019-06-10.zip' and put them in 'C:\Desktop\unzipData'.

Since I have many zipped folders that contain text files, I would like each zipped folder to be unzipped into another folder with similar name.

For example, I have the following zipped folders on teh left and would like them to be unzipped into the folders on the right::

'C:\Desktop\zipData\2019-06-10.zip' unzip into 'C:\Desktop\unzipData\2019-06-10'

'C:\Desktop\zipData\2019-06-17.zip' unzip into 'C:\Desktop\unzipData\2019-06-17'

'C:\Desktop\zipData\2019-06-21.zip' unzip into 'C:\Desktop\unzipData\2019-06-21'

Q2: Is it possible to extract the zipped file into a folder with the same name as zipped folder?

Thanks for your help!

The documentation of unzip is a bit unclear on the effect of locale, all it has to say is "To extract a zip file that contains non-7-bit ASCII characters, extract the file on a machine that has the appropriate language/encoding settings". Matlab's documentation on locale setting is inadequate, but see this page. I'm not sure how slCharacterEncoding affects matlab locale, it seems to be a simulink function.

As for unzip into a specific folder with the same name as the zip file, simply pass that name as the output folder:

sourceroot = 'C:\Desktop\zipData';
destroot = 'C:\Desktop\UnzipData';
zipfiles = {'2019-06-10.zip', '2019-06-17.zip', '2019-06-21.zip'};
for fileidx = 1:numel(zipfiles)
    [~, basename] = fileparts(zipfiles{fileidx});
    unzip(fullfile(sourceroot, zipfiles{fileidx}), fullfile(destroot, basename));
end
