[BUG] - 'gbk' codec can't decode byte 0x8c in position 2: illegal multibyte sequence When use GraphIndex
Description
When I try to build a graph index, I uploaded a PDF file and started building the index. During this process, the following errors will occur:
Indexing [1/1]: small_test.pdf
=> Converting small_test.pdf to text
=> Converted small_test.pdf to text
=> [small_test.pdf] Processed 2 chunks
=> Finished indexing small_test.pdf
[GraphRAG] Creating index... This can take a long time.

Encountering same issue using GraphRAG indexing. The UI doesn't provide enough information for debug, nor can I find any logging for it in the console, or a log for debugging GraphRAG indexing process
The same pdf does just fine in normal indexing process
