UTF-8 log entries aren't processed
Open, HighPublic


When a log entry contains UTF-8 character, it's not published.

The suspects are our TCL code (write JSON) and JsonMapper (read JSON), but this last library can handle UTF-8 in rNOTIF code.

Bogus log entry

[Ysul] Manual port upgrade to nano 4.2 — "Tax the rich, pay the teachers"

Replacing the UTF-8 character by the ASCII character - works fine.

When the payload generated by rVIPER Wearg/ServersLog.tcl has been tested with Postman, it works fine.

The eggdrop environment is set like this:

$ env
06:37:23 <Wearg> LANG=en_US.UTF-8
06:37:23 <Wearg> MM_CHARSET=UTF-8
06:37:23 <Wearg> LC_ALL=en_US.UTF-8

A workaround could be to encode UTF-8 characters in the JSON payload, a choice rather popular in JSON libraries.
