You are the first person interested enough to ask about it here. I intentionally do not include the symbol catalog in the plugin to avoid copying anything significant directly from Amazon.

The format of the kfx_symbol_catalog.ion file should be:

$ion_1_0
$ion_shared_symbol_table::
{
  name: "YJ_symbols",
  version: 10,
  symbols: [
    "language",
    "font_family",
    "font_style",
    ...
    "standalone_entities",
    "document_regions",
    "yj.user_margin_bounds"
  ]
}

Where ... is replaced by around 800 additional symbols.

The full list of symbols can be obtained by decompiling the Java file EpubToKFXConverter-4.0.jar, which is part of Amazon's Kindle Previewer software, using a tool such as CFR.

In version 3.86 of the Previewer the enumeration corresponding to the symbol table (b_0) can be found in the class com.amazon.kaf.c.b. Those names will be different in other versions of the Previewer due to Java obfuscation.
