pdf reading

[dunkel000]

When parsing a pdf document, It came up with this codec error.

Tool Input: {'path': '/economics/economics.pdf'} Tool Result: Error reading file: 'charmap' codec can't decode byte 0x81 in position 169: character maps to <undefined>

Is there any workaround? in the desktop app can easilly access pdfs.

Another similar error generating a markdown file with formulas:
Tool Result: Error creating file: 'charmap' codec can't encode character '\u03C0' in position 1706: character maps to <undefined>
