chelsealong 67ce9cbf1c Fix crash loading quantized checkpoints with all-NUL comfy_quant markers ... Some quantizers mark unquantized layers in a mixed-precision checkpoint with an all-NUL comfy_quant placeholder tensor instead of omitting the key. json.loads() misdetects the leading NUL bytes as UTF-32 and raises UnicodeDecodeError; once that decode is patched around, the resulting empty {} config still fails with "Unknown quantization format" because the loader always requires an explicit format for any present marker. Treat an all-NUL marker as if comfy_quant were absent so the layer loads as a plain unquantized weight, matching the official MiniMax H3 nvfp4 AWQ text encoder.
