26.4. Character set conversion

Table of Contents

It is recommended to normalize logs to UTF-8. The xm_charconv module provides character set conversion: the convert_fields() procedure for converting an entire message (all event fields) and a convert() function for converting a string.

Example 98. Character set auto-detection of various input encodings

This configuration shows an example of character set auto-detection. The input file may contain differently encoded lines, but by invoking the convert_fields() procedure, each message will have the character set encoding of its fields detected and then converted to UTF-8 as needed.
