Description
Name and Version

On Windows:
Currently, llama.cpp attempts to open GGUF files using fopen, which fails when the path contains Cyrillic characters. gguf_init_from_file: failed to open GGUF file
'D:\Загрузки\models\llm\olmOCR-2-7B-1025-Q4_K_M.gguf'.
For example, any ASCII characters are not supported, and the app throws an error. This means that any "Russian," "Chinese," "Korean," or any other characters in the path faild to load model.
