How to send an ansi encoded file

[smaktacular]

I tried to send a 7zip file, which is likely ANSI encoded (according to notepad++), using the < operator. The webservice could not properly decode it.
Afterwards I tried postman and the same file could be uploaded.

1. What would be the correct way to tell the extension about the ansi encoding? <@Ansi does not work as far as I can tell...
2. What other options instead of latin1 (from the docs) are valid ?

The NodeJS encodings are supported. ansi is not included, use ascii instead. However, when reading in using <, no encoding is actually needed. Here the byte[] is processed directly.
