a的相反是什么？ [英] What's the opposite of a nbsp?

问题描述

A & nbsp; 是一个不允许换行的空格。

A   character is a space which doesn't allow for line breaking.

<p>lorem ipsum here&nbsp;are&nbsp;some&nbsp;words and so on</p>

| lorem ipsum                |
| here are some words and so |
| on                         |

有什么相反的？也就是说，一个字符不会作为空格呈现，但可以用于换行。

What's the opposite of that? That is, a character which is NOT rendered as a space, but CAN be used for line breaking.

<p>foo supercalifragilisticexpialidocious bar</p>
<!--   put char here ^   and here ^ -->

|foo supercalifragi |
|listicexpiali      |
|docious bar        |

or with wider size:

|foo supercalifragilisticexpiali   |
|docious bar                       |

我知道软连字符，但为了我的目的，我具体做不是

I'm aware of the soft-hyphen character, but for my purposes, I specifically do not want a hyphen added at the break.

推荐答案

您需要unicode字符ZERO-WIDTH SPACE（\\\​）。

You want the unicode character ZERO-WIDTH SPACE (\u200B).

您可以使用&＃8203; 或&＃x200b; code>。

You can get it in HTML with ​ or ​.

显式休息和非休息：

Explicit breaks and non-breaks:

LB7：不要在空格或零宽度空格之前中断。

LB8：在零宽度空格之后的任何字符之前，即使一个或多个空格插入，也会分隔。

LB7 : Do not break before spaces or zero width space.
LB8 : Break before any character following a zero-width space, even if one or more spaces intervene.
