    <p>Ok, I've done some research on the subject but as the title indicates I'm no expert. So here's the problem: I'm extracting some text from pdfs using python and the lib pdfminer. </p> <p>I've only tried documents with latin characters and it works well in most cases, except if the font is not latin/western. The document that bugs me now is using latin characters from a japanese font. Adobe tells me the encoding is <code>Adobe-Identity</code>. All I get is the cid of the char and I can't find the cidmap related.</p> <p>I know I'm not using the right terms, I mean the pdf tells me <code>cid=3</code> and I know the char is a space. I've manually written a map for the chars in the range <code>0x00-0xFF</code>. Some sources tells it matches the "mac-roman" encoding, other disagrees. Other sources says it match OpenType mapping but I couldn't find anything beyond <code>0xFF</code>. And I've got cids >3000.</p> <p>You can tell I'm very confused, so you're invited to correct my terminology but what I'd want is a map that matches my own but extended for the range <code>0x0100-0xFFFF</code>.</p> <p>ETA: the link to the bugging pdf <a href="http://www.sas.upenn.edu/~jtigay/JapanVol.pdf" rel="nofollow">http://www.sas.upenn.edu/~jtigay/JapanVol.pdf</a><br> ETA2: I found this <a href="ftp://ftp.oreilly.com/pub/examples/nutshell/cjkv/adobe/aj14.tar.Z" rel="nofollow">ftp://ftp.oreilly.com/pub/examples/nutshell/cjkv/adobe/aj14.tar.Z</a> the cid2code.txt within the archive is the kind of map I'm looking for. But for all those fonts the cid column seems "shifted" by two: cid1 maps to space.<br> ETA3: corrected encoding</p>

    1. COYour file [JapanVol.pdf](http://www.sas.upenn.edu/~jtigay/JapanVol.pdf) does not really match your description. The only fonts in there using Adobe-Japan1 are HiraKakuStdN-W4 and RyuminPr5-Regular, and for the former one the embedded glyphs are the digits '0' through '9' and for the latter one only '-', '1', and '3'. There especially is no space glyph embedded for them. Thus, when you say *the pdf tells me cid=3 and I know the char is a space,* you are **not** inspecting glyphs of a font with Adobe-Japan1 CIDs.

    2. COErr, I'm so confused it's really hard to explain my problem. There's a "Times" font in that file too and it is that one which is unreadable. Calibre can't convert it (blank pages), and when I open the doc with pdfminer I only get CIDs instead of unicode chars. I have fully "decoded" what I call a map: when I replace the cid=3 by a space (and so on) I can rebuild the text. And I'm sorry to have so much blank spaces in that map. The greatest CID in that doc is 3013. I don't want to populate the map manually. ETA: it's encoding is Adobe-Identity, you're right

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
