告诉HN：Perplexity在会话导出时有未指定的字符限制
大家好，
我发现，导出 Perplexity 会话为 PDF 时，当页面数达到约 90 页时，会导致大量内容丢失，这一点我是通过亲身经历得出的。
在就此问题提交工单后，与客服的简短对话并没有提供帮助，反而让我感到困惑。客服表示“导出为 PDF”功能仅导出单个“线程”，而要导出整个会话，必须逐个选择并导出这些所谓的线程。这显然是错误的。
实际上，无法通过右上角的三点菜单/导出为 PDF 选项选择线程。对不同会话进行测试，从 1 页到 170 页的导出结果显示，线程并不相关。
在 90 页以下的导出通常*能够保留所有内容，而 93 页的导出却没有保留，但 95 页和 170 页的导出则保留了所有内容。这表明字符限制（如果这是原因的话）是可变的，因为 170 页的内容几乎肯定会比 90 页多。
无论原因是什么，根本问题在于，在当前用户界面下，由于缺乏文档、通知等，数据丢失是不可避免的。
*我注意到在提交工单后情况有所变化，已经进行了修改。之前的情况更糟，现在稍微好一些，但问题依然存在。

Hello all,<p>I discovered, the hard way, that exporting Perplexity sessions to PDF results in substantial content loss when the page is ~90 pages.<p>After opening a ticket on the matter, a brief dialogue with a rep proved unhelpful and confusing. It was stated that the Export as PDF feature only exports individual "threads", and that to export an entire session, each so-called thread must be individually selected and exported. This is simply wrong.<p>In practice, there is no method to select threads through the Top-Right/ 3-dot menu/Export as PDF option. Testing this with various sessions from 1 to 170 page exports showed no indication that threads were relevant.<p>Exports under 90 pages tend* to retain all content, while a 93-page didn't, but a 95 and 170 page export did. This indicates that the character limit (if that's the cause) is variable, as 170 pages is almost guaranteed to contain more characters than 90.<p>The fundamental point here, whatever the cause, is that data loss is inevitable under the present UI with its absence of documentation, notices etc.<p>*I observed changes after submitting the ticket and modifications have already been made. The situation was worse before, and now less worse, but still applies.
