説明

Name and Version

b7539 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.

Problem description & steps to reproduce

On Windows, create a directory with Cyrillic characters, e.g.:

  1. for exempel D:\Загрузки\models\
  2. Place a .gguf model file inside.

調査方針
Investigate the file loading functions in llama.cpp, particularly where `fopen` is used to open GGUF files. On Windows, `fopen` does not support UTF 8 paths in all locales. The fix likely involves switching to ` wfopen` or using `CreateFileW` with wide character strings. Review existing code in `gguf.cpp` or similar files that handle file opening. Check if there are any existing platform specific macros or if the codebase uses `std::ifstream` which might handle it differently. The issue comments may provide additional context or suggested approaches.
