Ghostscript字体转换问题

Question

所有

我在pdf中遇到字体问题。在原文中，它显示一个实线，但如果我复制它，我在剪贴板上得到这个ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ。

这表明我使用了一些特殊字体，这很好。问题是我使用这个pdf作为ghostscript的输入，并且该行变成了一堆包含X的盒子。

经过一番搜索，我遇到了this answer。 -c命令成功删除了这些框，但该行仍然缺失。

在Windows 7 64位系统上运行gswin64c.exe -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=output.pdf USA_15238-2897_5853101.pdf，我得到以下输出：

将Windows字体文件夹添加为字体路径开关可以查找字体，但不会将行修复为问题。

运行gswin64c.exe -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=output.pdf -c ".setpdfwrite <</NeverEmbed [ ]>> setdistillerparams" -f USA_15238-2897_5853101.pdf会产生这个：

但该行现在是pdf中的空格。如果我复制并粘贴它，我会得到─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─。

我需要添加什么ghostscript开关来保持原始pdf的行？

Answer 1

如果没有看到您的PDF文件，就无法说出发生了什么。请注意，Ghostscript转换为PDF后，无法保证复制+粘贴无效，尤其是。

由于您已有PDF文件，为什么要将其转换为PDF？

最可能的问题是将Courier替换为Courier-New，但没有看到该文件我无法确定。
