Out of all the words with an umlaut, why this one?

[n00b001]

llama.cpp/convert_hf_to_gguf_update.py

Line 279 in 84ec8a5

"Führer",

And if you want another option:
#11600

Because it is the first word with umlaut that appears in the WikiText-2 dataset that we use to test tokenizers and at that time it was causing the BPE tokenizers to fail, so I added it to the list, similar to all other failing words.
