Decompress can´t handle "á" (ERROR Decompress ... Illegal char <?>

KNIME Analytics Platform
1

Using node “Decompress File” to decompress file downloaded from

https://download.inep.gov.br/microdados/Enade_Microdados/microdados_enade_2019.

I get the error:

ERROR Decompress Files 3:2 Execute failed: Illegal char <?> at index 137: <>\1.LEIA-ME\Dicion?rio de vari?veis dos Microdados do Enade 2019.ods

It seems that Decompress File can´t handle accented a, maybe other characters too. No problems with traditional zip/rar tools.

Hi @xexeo , this is most definitely a bug.

What’s really happening here is that, the accented characters are not being recognized, and are being taken as “?”, and “?” is not a valid character for a filename. So it’s complaining because it will not be able create a file with “?” in the name.

Somehow, when Knime is reading the index of the file, it’s not reading the accented characters.

@xexeo as a workaround you could try and unzip the file with R (1|2):

@ipazin would be great if this ticket could address the problems with several special characters and decompression.

Hello @mlauber71,

in general I think that is a way of working but if you know more special characters that cause issues I can add them into ticket :wink:

@ipazin if you could add empty folders and folders with special characters it would be great.
