It seems there is no way to display UTF-8 encoded ePub files in DE 1.5 correctly. If uncompressed, HTML content looks fine in a browser. In DE all common accented characters are substituted with ? character.

There are two similar topics on this forum:
http://www.adobeforums.com/webx/.59b6343e
http://www.adobeforums.com/webx/.59b60d2d

My ePub file was generated via DocBook XSL Stylesheets and there is no problem to display it in FBReader.

I suppose it is caused by default font, which contains probably very limited range of characters. Unfortunately there is no way to select the better one (as it is possible in FBReader).
Something about changing the default font was "discussed" here: http://www.adobeforums.com/webx/.59b5e8b7

If I met this issue 10 years ago, I would understand. If anybody in these days offer software for reading text with no support for non-roman languages, it is hard to believe.

What I would suggest is to deliver DE with any very complete font, for example MinionPro (latin, cyrillic, CE, greek etc.). If this is impossible, please add a feature for selecting the default font.

If I am totally wrong, clarification of this issue is welcomed.

Unfortunately, version 1.7 doesn't help in this, although there is mentioned somewhere on product pages: "Digital Editions ... can display content in a wide range of languages."

For glyphs not supported by our current faux fonts, to ensure that the user can view them regardless of system settings (ie desktop with and without the system fonts there, and devices that may not have the system fonts at all), you will want to embed the fonts in the ePub file.

Jim,

There are two problems with font embedding in epub:

1) Many fonts are over 300K, the file size limit to pass ePub Check (and therefore work on most ePub reading systems).

2) As far as I know, licensing is still unclear. If I want to distribute an ePub commercially, am I restricted by the licenses of the fonts I want to embed? I have seen no definitive answer here.

From Jim Lester

"We are looking at other mechanisms to download the fonts on demand, but this is fairly low in priority compared to long laundry list of other features we want to do."

It's been 3 years. Fairly low in priority means not at all?

Will we ever see better unicode support?

Hi Jim,

I didn't know there is possible such mechanism. Thanks for your clarification. I'll look at it.

Hi Jim--

Thanks very much for the explanation on this...

You know, Adobe could save us all a lot of time if the default faux fonts would include more unicode support....

(I've spent probably a day overall trying to figure out what the issue is, and now I will spend the rest of the day learning/testing embedding a custom font in an epub, just for Digital Editions...)

Even Mobipocket and Kindle are getting these entities right in the three books I'm working on, with their default fonts. (We're not talking about super-obscure characters. Try "Milosevic" with the proper characters, and you get a ? in DE.)

Is there any chance Adobe can get the default fonts smarter in 1.8..?

Thanks for any help/thoughts on this front...I'm sure I don't understand all the issues...it just seems like such an obvious straightforward thing to fix.

Full Unicode font support for all glyphs would bloat the Digital Editions download from ~6Mb to around 32 to 40 Mb.  This is not something we are anxious to do.  We are looking at other mechanisms to download the fonts on demand, but this is fairly low in priority compared to long laundry list of other features we want to do.

Jim,

I actually did not understand how can I view the cyrillic text from a ePub file. Now I'm seeing "?" or other chars, but not the actual cyrillic letters. The authors say the file was written using Cyrillic Windows 1251 chars set.

I think none of us is requesting full Unicode. For example Tahoma supports many languages and it has 660 kB only.

Is there any chance of better Unicode Support anytime soon in Digital Editions?

I'm looking for Latin Extended Additional, Latin Extended A, etc

Even within Latin Extended A, there seems to be support for some characters but not others.

Is there a list somewhere for what EXACTLY is supported as of now?

Seems like no one at Adobe cares about this issue?

Well, I also think it is a serious problem. I am from the Czech Republic and it is an issue for many people wanting to read on ebook devices. There are several ways how to overcome the limitation (using built in font, change the font in CSS) but all these are typically for technology savvy people, the outcome is dependent on the reading device or the epub is quite large (with all fonts included - also for Times New Roman).

And the number of potential consumers in countries with non-English characters is quite big so I do not understand the priority setting.

Best regards,

Viktor
