Screenshot

If I have an East-Asian character in my (predominantly English) document, followed by a quotation mark (opening or closing), the quotation mark takes the font settings from the "Asian text font" section of the style definition.  This results in very ugly copy.


Steps to reproduce:
1. Type some western text into LO Writer, surrounded by quotation marks (e.g. "sun").
2. Move the cursor to before the opening quotation mark, and type (or paste -- the IME is not relevant) an East-Asian character (e.g. 日).


Current behaviour:
The initial quotation mark takes the settings from "Asian text font" instead of "Western text font".  The behaviour is the same if a (normal-width, western) space comes between the East-Asian character and the opening quotation mark.


Expected behaviour:
The opening quotation mark, being surrounded by a normal-width space on one side, and a Latin letter ("s" in this case) on the other, should take the "Western text font" settings.


The only way to "work-around" this problem is to select the characters that have been rendered incorrectly and manually force the application of the "Western text font" settings.  Of course, this breaks if "Clear Direct Formatting" is used.

It's not clear to me why typing an opening quotation mark immediately after an East-Asian character results in the insertion of Asian punctuation (e.g. 「 or 『).  If I wanted Asian punctuation, I would, of course, type Asian punctuation.  I don't know if this is connected.

I'm currently using LO Version 4.0.4.2 (Build ID: 400m0(Build:2)) on Linux Mint 14 amd64, but the problem has been around as long as I can remember and on every platform I've tried.

test cases of English and Chinese quotes

I confirm this bug in LibreOffice 4.0.5.2 and 4.1.1.2.

I did some test in the attached file, see the highlighted part. Quotes are incorrect when in the first line or after a different language.

When disable "double quotes replacement" in autocorrection option, everything is OK, so its a replacement problem.

Today I tested attachment 85096 [details] in 4.3.0.1, 
And it seems that it's getting worse.
All the start quote which are at the beginning of paragraph are always shown as "half-width", regardless of whether the following chars are westen or Asian.

I think using “East Asian text font” is more suitable.

@simon
does this helps?

Four years after the initial report, this bug still exists in LibreOffice 5.3.4 (running on Windows) with a mix of East Asian (CJK) and non-CJK fonts and text.

This also happens to languages like Thai (Complex text layout), please see attached PNG file.

It's actually quite annoying ...

Oh I made a misunderstand, but I thought that is more proper name.

As my suggestion, we can set the default language at the document level firstly, for example, in content.xml we can save the attribute as: 
<office:document-content lang="zh-CN">
Or alternatively, we save the locale language at settings.xml, then we can try to use CJK fonts to render such punctuations by default if LibreOffice recognized that, until we set another default language to a paragraph.
