Random special characters returned instead of dashes or apostrophe

### Bug

When parsing PDF files, I get strange output text for some simple elements like dashes or apostrophes. I observed:
- '¥' instead of '-'
- 'Ð' instead of '-' in another file
- 'Õ' instead of '‘' (apostrophe)
- 'Ô' instead of '"'

### Steps to reproduce

Run docling conversion on the following PDF:

[docling_test_symbols.pdf](https://github.com/user-attachments/files/20925634/docling_test_symbols.pdf)

Input:

Output in markdown:
```
## How?

## Similarities

- ¥ test2

This is a testÕ
