PDF - Japanese font, English font - don't play well together
We're looking for a solution to problems in the PDF output of the Japanese translation of our help file. (WinHelp output works fine, with none of the issues below.)
PDF manual template: Classic_manual.mnl
Font mode: embed TrueType fonts
The font is Segoe UI* (selected by Tokyo-based translator).
We're getting overlapping and mis-alignment in the PDF output of our Japanese translation where both English and Japanese appear on the same line. Plus, there are issues with toggled content (light blue-green background). Excerpt:
Where English words appear in the same line as Japanese in the text, the English content drops ~12-14 points (printer's measure) / ~5/16 in [~10mm] (physical measure) below the Japanese line and superimposes itself over the next line of Japanese.
In toggled text, only the bottom 1/8 or less of the first line of toggled content is visible.

Re: PDF - Japanese font, English font - don't play well toge
Hi Dave,
There have been some issues with spacing in the new PDF engine that are being worked on. Please try the current interim version of 7.3.5 to see if this helps:
https://www.helpandmanual.com/download/ ... p-v735.exe
This being said, there are also frequent problems with mixing Asian and Latin text on the same page, more when they are mixed in the same paragraphs. When you are using the same font for both languages it's essential that you use a full Unicode font that includes all the characters used for both languages. If even a single character is not available in the font, Windows replaces the entire font with an alternative or even graphic glyphs, and the results can be very odd.
Another thing to check is the font embedding. Many issues in Asian PDFs can be dealt with by changing the font embedding setting to either CID Fonts, or Type 3 Fonts. Try CID first, because that will provide slightly crisper text and if it works it is a better option.

Re: PDF - Japanese font, English font - don't play well toge
If I install on a virtual machine, will I be able to license/activate it? Or can you say more or less confidently that 7.3.5 is bug-free, and will be a problem-free upgrade -- or that it's possible to move back to our current 7.3.4?Tim Green wrote:Please try the current interim version of 7.3.5 to see if this helps:
That last sounds like an impertinent question, but smooth H+M running (and it has been a remarkably bug-free run for us) is important for various reasons right now.
I'll try these options first, before installing 7.3.5.Another thing to check is the font embedding.

Ignore impertinent questions -
Embedding as Type 3 worked!

Re: PDF - Japanese font, English font - don't play well toge
Hi Dave,
Good to hear it worked. Installing our released betas should always be pretty much trouble-free (I don't work with anything else) and you can always return to the previous version. All you need to do is reinstall the release version "on top". Help+Manual is very robust as far as that goes -- even if you were to go and delete ALL its Windows Registry entries it would simply shrug its shoulders and re-build them the next time it starts.
However, it would be very helpful for us if you could also confirm that the current beta also solves the problem with your Latin + Japanese combination. You can install on a VM to do that if you want. It will run in fully functional free trial mode if you don't register. You will get a copyright notice and some scrambled words in the PDF output, but you should still be able to test your issue.

Sure. I can't do it today as we're in a major blizzard and likely to lose electrical power.
I'll tackle this as soon as consistent power is available.
I assume that I should use 'embed as trutype font' ? Any other settings or configurations that I should be using?

Re: PDF - Japanese font, English font - don't play well toge
Sorry, no change.
Downloaded & installed 7.3.5. (Double-checked after getting the negative result - it really was 7.3.5).
Ran our project as PDF with TrueType embedded.
Font is still Segoe UI, 11 point (body text/normal)
Got the original result - the English text baseline drops significantly below the Japanese, and the first line of text in toggles is truncated:

Hi Dave,
Thanks. It would be helpful if you could mail a small demo project illustrating this to support AT ec-software.com (replace the AT with @). We only need a .hmxz project file with a couple of affected topics for this, no other files.
