Subject: libreoffice-writer: Vertical text alignment problem with Japanese text
Date: Tue, 17 Dec 2013 21:52:59 +0900

[Message part 1 (text/plain, inline)]

Package: libreoffice-writer
Version: 1:4.1.3-1+b1
Severity: normal

The vertical text alignment always bothered me and made me use non-free
fonts.  Problem seems to be in several places.
 * libreoffice screen rendering
 * libreoffice PDF/printing output
 * reference font cordinates of Japanese fonts seems to be inconsistent

Almost all FreeFonts cause screen arrangement problem while its PDF
looks better (not perfect).

MS fonts are almost perfect for both (excluding FULL size Alphabet)

EPSON fonts are least problematic.

(Not included here but many Japanese fonts in the Windows 8 disk works
as good as MS font.)

I attache test odt file and PDF file generated by libreoffice.
(Containing screeshot so you know how things change)

Keep special attention on 2 alignment reference lines I placed.

The vertical line character for long sound has problem on some fonts and
these are font problem.

Since PDF file looks good enough, I think screen rendering engine of
libreoffice has room to be improved.

Regards,

Osamu

If I understand correctly, the attached "Sample PDF output" shows a small sample of Japanese text displayed in a number of fonts (both free and non-free). The inset screenshot shows how LibreOffice displays the text in the running program, while the main document shows the result of LibreOffice export to PDF. Correct?

On this system, it appears that I currently have DROID SANS Japanese available (the rest are being substituted). Can you demonstrate the problem using fonts that ship/package with stock Debian/Ubuntu/LibreOffice?

It also appears that the provided PDF contains a different list/different arrangement of the fonts as compared to the ODT. Could you please harmonize these two? Thanks

Status -> NEEDINFO

Yes, I think also.

I forward what a Debian user reported. I have not looked in depth document, I do not feel competent in Japanese… I will try to learn more from the user.
