Filee-2.2.0-linux-arm64.tar.gz：Tesseract failed (exit 1). Tesseract Open Source OCR Engine v4.0.0 with Leptonica Can not open file "tessdata//pdf.ttf"!

[zsjzt]

Filee-2.2.0-linux-arm64.tar.gz: After enabling OCR（简体中文）, the call to the Tesseract open-source OCR Engine v4.0.0 failed, with an error message indicating that the file "tessdata//pdf.ttf" cannot be opened. After checking, the file actually exists. It is suspected that there is a path concatenation error, where multiple redundant "/" characters are incorrectly added in the path "tessdata//pdf.ttf". Please check and fix this issue.

Filee-2.2.0-linux-arm64.tar.gz：启用 OCR（简体中文） 后，调用Tesseract Open Source OCR Engine v4.0.0失败，提示无法打开文件"tessdata//pdf.ttf"，核实后，文件实际存在，怀疑是路径拼接错误，"tessdata//pdf.ttf"里面多了个“/”，请检查修正。

The // is harmless. Filee runs Tesseract with --tessdata-dir set to a temporary folder that holds only the language file. Tesseract 4.0.0 reads pdf.ttf from that folder.

• Tesseract 4.0.0 (Debian buster) - same error
• Tesseract 5.3.4 (Ubuntu 24.04) - PDF OK

Install Tesseract 5.

Thanks for the report, @zsjzt, and thanks @g4lb for narrowing it down. Since this is a bug in Filee rather than a question, I've moved it to #N so it can be tracked and fixed there.

The // isn't the cause. Filee gives Tesseract a temporary data folder that holds only the language file, and Tesseract 4.0 looks for pdf.ttf in that folder when it writes a PDF. Newer versions don't need that file, which is why 5.x works. Until it's fixed, installing Tesseract 5 is the workaround.

已在 Filee 2.3.0 中修复。

上面提到的 "#N" 是 #1040。修复是 #1043：使用 Tesseract 4.x 生成 PDF 时，Filee 会把 pdf.ttf 一起放进临时的 tessdata 文件夹，所以系统自带的 Tesseract 4.0 / 4.1 也能正常输出 PDF。

• 下载：https://github.com/KnifeLemon/Filee/releases/tag/v2.3.0 （Filee-2.3.0-linux-arm64.tar.gz）
• 不需要再改装 Tesseract 5。

如果更新后还有问题，请在 #1040 留言。

Fixed in Filee 2.3.0.

The "#N" above is #1040, fixed by #1043: when Tesseract 4.x writes a PDF, Filee now puts pdf.ttf into the temporary tessdata folder too, so the system's Tesseract 4.0 / 4.1 writes the PDF fine.

• Download: https://github.com/KnifeLemon/Filee/releases/tag/v2.3.0 (Filee-2.3.0-linux-arm64.tar.gz)
• Installing Tesseract 5 isn't needed any more.

If it still fails after updating, please comment on #1040.
