Ghostscript字体转换问题

Question

全部，

我遇到了pdf中字体的问题。在原文中，它显示了一条实线，但是如果我复制它，我会在剪贴板上获得这个ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ。

这表明它是一些特殊的字体被使用，这会很好。问题是我使用这个pdf作为ghostscript的输入，并且该行变成了一堆带有X的框。

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

运行在Windows gswin64c.exe -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=output.pdf USA_15238-2897_5853101.pdf 7 64位系统，我得到下面的输出：

添加Windows字体文件夹的字体路径开关允许查找字体，但不能解决行盒问题。

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

但现在该行是在PDF空间。如果我复制并粘贴它，我会得到─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─。

我需要添加哪些ghostscript开关以保持原始PDF格式的行？

没有看到您的PDF文件就无法说出发生了什么。请注意，在Ghostscript转换为PDF后，复制+粘贴并不能保证能够正常工作，尤其是。

既然你已经有一个PDF文件，为什么你把它转换为PDF？

最可能出现的问题是将信使换成信使 - 新的，但没有看到文件我不能确定。
