I want to remove diacritics&nbsp; on document level (before tagging). Unfortunately removing diacritics is part of string manipulation and so it cant be used for documents. Perhaps the replacer node might be helpful but then I need regular expressions.

Besides the punctuation erasure node&nbsp;removes only the well known punctuations but no strange characters after converting documents before I load them to Knime. Is a solution for this available?

Additional question: After preprocessing documents I want to read the results. Unfortunately if I try to write the table with the document to disk only an extract of the first part can be seen. The same when I convert the document to string. How can I read the processed documents?

Hi Taita,

there is no dedicated node to remove diacritics from documents / terms so far. The only way (without using the RegEx Filter) is to do the string manipulation before you create documents from the strings.

Cheers, Kilian
