Apache FOP: Displaying UTF-8 Characters in PDF (without embed?)
提问by Tyler D
I'm trying to use FOP to export a PDF with UTF-8 characters, preferably without needing to embed the font.
The following code:
我正在尝试使用 FOP 导出带有 UTF-8 字符的 PDF，最好不需要嵌入字体。
以下代码：
<fo:block font="10pt Helvetica" text-align="justify" space-after="10pt" space-before="8pt" keep-with-previous="auto" keep-together.within-page="auto">
<fo:block font-weight="bold" color="gray">Summary</fo:block>
<fo:block text-indent="1em" keep-with-previous="always">
<fo:block text-indent="1em" space-before="4pt">
<fo:block text-indent="1em" space-before="4pt">私はガラスを食べられます。それは私を傷つけません
</fo:block>
</fo:block>
</fo:block>
</fo:block>
produces #################### in the PDF. I'm aware of the issue: http://xmlgraphics.apache.org/fop/faq.html#pdf-characters
在 PDF 中生成 ###################。我知道这个问题：http: //xmlgraphics.apache.org/fop/faq.html#pdf-characters
When I go under Document Properties->Fonts, the Helvetica font is listed with 'Encoding: ANSI'. Is there a way to change this?
当我进入“文档属性”->“字体”时，Helvetica 字体与“编码：ANSI”一起列出。有没有办法改变这种情况？
If I were embedding, what would be the best way to do so without having access to Helvetica.ttf? I've tried using DejaVuSans, but I end up with squares in place of the # signs.
如果我要嵌入，那么在无法访问 Helvetica.ttf 的情况下这样做的最佳方法是什么？我试过使用 DejaVuSans，但我最终用方块代替了 # 符号。
Note that this is not a one-time use from the command line (that would be a start), but an extension to an existing app. I'm trying to support UTF-8 characters without too much complexity.
请注意，这不是从命令行一次性使用（这将是一个开始），而是对现有应用程序的扩展。我正在尝试支持 UTF-8 字符而不会太复杂。

AFAICT, the fonts included in the PDF specificationonly include characters from ISO-Latin-1. If you want a character that falls outside of those defined in Annex D: Character Sets and Encodings, then you are expected to embed the font.
AFAICT，PDF 规范中包含的字体仅包含 ISO-Latin-1 中的字符。如果您想要的字符不在Annex D: Character Sets and Encodings 中定义的字符范围内，那么您应该嵌入该字体。
