双向文本，浏览器表现不佳 [英] Bidirectional text, browsers behaving badly
问题描述
在许多语言的书名概述中，我在另一个帖子中写了一些关于某些标题的问题
这是从右到左书写的，如阿拉伯语和希伯来语。
有问题的页面是utf-8。理想情况下，Unicode BiDi
算法应该处理任何从右到左的文本。它好b / b
效果很好，除非标题以数字或标点符号开头，
没有固有的方向性因此需要
它们出现的父元素的方向性。
根据
http://www.w3.org/International/arti...-markup/#where ，
插入一个从右到左的标记应该可以解决问题。或者，你
可以使用带有dir属性的额外标记。
我把一个小测试页放在
http://www.phys.uu.nl/~gdevries/test/比迪/ testbidi.html 。它显示了一个
表，其中包含三种语言的标题。对于每种语言，标题都是< ul>中列出的
。希伯来语标题以20,000开头。是导致问题的那一个
。
唯一适用于我测试的所有浏览器的解决方案（Opera
7.54，IE6，FF）是添加一个额外的< cite>在每个标题周围。
仅使用rtl标记在Opera中不起作用，在该标记之前用
零宽度空间解决了Opera中的问题，但是让IE感到不安。
有人能提出他们的意见吗？关于为什么Opera无法处理的任何想法
正确的rtl标记？
[1] BTW，土耳其的标题实际上并没有提到Vingt mille谎言
sous les mers"，但是Deux ans de vacances;我将这些包括在内以使
明确表示可以用各种*脚本*编写一个*语言*，并且必须给出
指示方向性的明确指示
在标题级别，而不是一种语言的所有标题。

In an overview of book titles in many languages, which I wrote about in
another thread, I''ve run across a problem with some titles in scripts
that are written from right to left, like Arabic and Hebrew.
The page in question is served as utf-8. Ideally, the Unicode BiDi
algorithm should take care of any right-to-left pieces of text. It
works well, except where a title starts with a number or punctuation,
which don''t have an inherent directionality and therefore take the
directionality of the parent element they occur in.
According to
http://www.w3.org/International/arti...-markup/#where,
inserting a right-to-left mark should do the trick. Alternatively, you
could use extra markup with a dir attribute.
I put together a little test page at
http://www.phys.uu.nl/~gdevries/test/bidi/testbidi.html. It shows a
table with titles in three languages. For each language, the titles are
listed in a <ul>. The Hebrew title starting with "20,000" is the one
causing the problem [1].
The only solution that works in all the browsers I tested in (Opera
7.54, IE6, FF) is to add an extra <cite> around each of the titles.
Using only a rtl mark doesn''t work in Opera, preceding that mark by a
zero-width space solves the problem in Opera, but upsets IE.
Could anyone offer their comments? Any ideas on why Opera can''t handle
the rtl mark correctly?
[1] BTW, the Turkish titles don''t actually refer to "Vingt mille lieues
sous les mers", but to "Deux ans de vacances"; I included these to make
clear that one *language* can be written in various *scripts*, and that
indication of the directionality, when explicitly given, must be given
at the title level, not for all titles in one language together.

解决方案＃5工作正常Opera 8.02
粗略的Google表明Opera7的RTL支持较差，早期版本没有。
没有。
Solution #5 works fine in Opera 8.02
A cursory Google shows that Opera7 had poor RTL support and earlier versions
had none.

You might write "Bidi" or "BIDI"; but "BiDi" isn''t justified.
algorithm should take care of any right-to-left pieces of text.
The algorithm itself refers to certain Unicode control characters.
It is a common misbelieve that the bidirectional algorithm does
everything without control characters for you. On the contrary,
you are required to use Unicode control characters in text/plain
for certain constructions. The HTML equivalent for these control
characters is markup with the DIR attribute.
According to

Right. Inserting ‎ ‏ is easier but HTML markup is
safer and more suitable for the _markup_ language HTML.

Opera（和其他浏览器）在双向显示屏中被打破。
基于Mozilla的浏览器和Internet Explorer 6效果最好。
Mozilla和IE 6的区别在于，Mozilla（照例）是正确的。
Opera (and other browsers) are broken in their bidi display.
Mozilla-based browsers and Internet Explorer 6 work best.
Where Mozilla and IE 6 differ, Mozilla is (as usual) right.

这只是一个比较重的问题。在我的情况下，我保留所有标题（
78种语言，一些语言的数百种标题，在一个
数据库中。一个RTL标记很容易添加到那些几个需要它的标题
（即以数字开头的阿拉伯语或希伯来语标题）。但是添加
标记，例如< cite>（这在语义上是有意义的）会添加
几百个< cite>< / cite>到该页面，具体取决于用户想要显示的那些
语言。此外，我必须保持所有标题的方向性跟踪。当然，这是可行的，但是
是最明智的做法吗？

Slip of the keyboard...

It''s just a bit heavier kB-wise. In my case, I keep all the titles (in
78 languages, with hundreds of titles for some languages, in a
database. A RTL mark is easily added to those few titles that need it
(i.e. Arabic or Hebrew titles starting with a number). But adding
markup like <cite> (which would make sense semantically) would add
several hundreds of <cite></cite>s to the page, depending on which
language(s) the user wants to see displayed. Also, I would have to keep
track of directionality for all the titles. It''s doable, of course, but
is it the smartest thing to do?
" 20,000"
"20,000"
这意味着20.000 = 20.
如果你的意思是两万，那么写20& nbsp; 000

This means 20.000 = 20.
If you mean twenty thousand, then write 20 000
(ISO 31, ISO 1000)
我引用的标题就是它们在现实生活中的使用方式。所以如果< br $> b $ b book具有20,000的在封面上，我把20,000放在在我的清单中。
顺便说一句，你不会使用比'& nbsp;'/ b
歌剧（和其他）更小的空间吗？在他们的双向显示器中打破了。
I quote the titles exactly how they are used in real life. So if the
book has "20,000" on its cover, I put "20,000" in my list.
BTW, wouldn''t you use a space that''s a bit narrower than ?
Opera (and other browsers) are broken in their bidi display.
很可惜......
我猜最安全的方式现在就是使用标记。即使它有点重，但它有更大的可能性给出预期的结果，至少在所有浏览器都满足比迪烟要求之前，它们都是b $ b。 />
It''s a pity...
I guess the safest way to go for now is to use markup. Even if it''s a
bit heavier, it has a larger probability to give the intended result,
at least until all browsers have caught up with bidi requirements.
