Fixing RTF Conversion Issues

1. Unresolved Characters and Glyphs

If you see strange garbled syntax outputs like `\fcharset0 \b0`, our client-side extraction engine was unable to identify a proprietary font block. Opening the RTF in WordPad and saving a fresh copy often trims out MS-specific cruft.

2. Heavy Image Attachments Failing

RTF encapsulates images in hexadecimal clusters. For massive files exceeding 5 Megabytes in purely text-coded hexadecimal blobs, your browser might freeze while parsing it into valid base64 buffers. We generally enforce a 5MB threshold on RTF documents for browser safety.
