----------------------------------
Summary: Add an InferCharacterSet processor
Key: NIFI-4550
URL: https://issues.apache.org/jira/browse/NIFI-4550
Project: Apache NiFi
Issue Type: New Feature
Components: Extensions
Reporter: Matt Burgess
Priority: Minor
Sometimes in a NiFi flow it is not known what character set an incoming flow
file is using. This can make it difficult for downstream processing if the
processors expect a particular charset (whether the user can configure it or
not). There is a ConvertCharacterSet processor, but it expects an explicit
value for Input Character Set, when this might not be known.
I propose an InferCharacterSet processor, which would presumably use some
license-friendly third-party library (there is a discussion
[here|https://stackoverflow.com/questions/499010/java-how-to-determine-the-correct-charset-encoding-of-a-stream])
to guess the character set, perhaps adding it as an attribute for use
downstream in ConvertCharacterSet.
