3.1.8 Handling interlinear punctuation
3.1.8 行间标点的处理

1. Overview
Most punctuation marks in modern Chinese typesetting are interspersed between the text in a line, but the Proper Noun Mark (underline), the Book Title Mark (only for the type A wavy low line) and the Emphasis Dot need to be positioned between lines. These punctuation marks are known as “interlinear punctuation”. Of which, the Proper Noun Mark and the Book Title mark are known as [Interlines??] <-- I don't know how to translate 行间线.
1. 概述
现代中文排版的标点符号，大部分都随文字穿插在行内，但专名号（下划线）、书名号（仅指甲式的波浪线)、着重号要摆放在行与行之间，这些标点通称为「行间标点」。其中专名号（下划线）、书名号（仅指甲式的波浪线）合称为「行间线」。

Sentence spacing for ancient Chinese texts were all interlinear punctuation. Although the typesetting of ancient Chinese texts is beyond the scope of this document, it can still serve as a reference for the basic principles of interlinear punctuation.
传统中文古籍中的「句读」也都是「行间标点」。传统中文古籍排版虽然已经超出了本文档的范围，但是行间标点的基本原则可参照本节内容。

In vertical typesetting, the Interlines are positioned to the left of the text, while the Emphasis Dot is positioned to the right of the text. The situation where both these punctuation are applied to a run of text is known as [double-sided wrapping??] <-- I don't know how to translate 双面装. In horizontal typesetting, both the Interlines and Emphasis Dot are positioned to the bottom of the text. This situation is known as a [single-side wrap??] <-- I don't know how to translate 单面装. In principle, text typeset horizontally will not use double-sided wrapping.
直排时，行间线标注于文字左侧，着重号标注于文字右侧。像这样，文字两侧均加排行间标点的排版方式叫「双面装」。横排时，行间线、着重号均标注于文字下方。像这样，文字单侧加排行间标点的排版方式叫「单面装」。原则上，横排书不使用双面装。

2. General guidance
Under normal circumstances, a line of text will use the same font size. For these instances, single-sided and double-sided wrapping will generally behave as follows:
2. 通则
通常情况下，一行内文字使用同样的字号，此时，单、双面装的一般通则如下：

Regardless of single-sided or double-sided wrapping, as well as for horizontal or vertical typesetting, the line gap should always be consistent. This is in accordance to what was stated in section 2.3.5.4. During the initial typesetting design, the positioning of the punctuation must be taken into account such that sufficient space is allocated for the line gap. Forcing extra spacing in a single line containing interlinear punctuation must be avoided as much as possible.
无论单面装、双面装，也无论横排、直排，原则上行距应保持一致。这一点与 2.3.5.4 阐述内容一致。在最初设计基本版式时就必须提前考虑好行间标点的情况，并设置好足够大的行距。应尽量避免为了行间标点而强行局部撑大单行行距的做法。

To ensure appropriate positioning of interlinear punctuation, the line gap for single-sided wrap should not be smaller than half of the font-size, while the line hap for double-sided wrapping should not be smaller than 5/8 (=1/2+1/8) of the font size
为保证行间标点的摆放，单面装的行距不应小于当前字号的一半、双面装的的行距不应小于当前字号的 5/8 （=1/2+1/8）

Emphasis Dots should be center-aligned with its corresponding character; interlines should be correspond with the length and quantity of content they are marking out. As such, if there are multiple instances which need to be marked out with interlines, multiple interlines need to be used. Interlines must not be arbitrarily broken up, a single interline cannot be composed out of multiple fragments either. For example, if there are two adjacent Proper Nouns, even if the text being marked out is set solid, both Proper Nouns must be clearly marked with two Proper Noun Marks that are distinguishable from one another. In this instance, a single Proper Noun Mark must not be used, because this would cause the two Proper Nouns to be misunderstood as a single Proper Noun.
着重号应与所指示的字符居中对齐；行间线应与所标注内容的长短、数量均要保持一致，即，有几个标注项目就用几条线段，不能任意从中断开，也不能用多条线段拼接组合。比如，相邻的两个专名，即使所标注的正文汉字是密排，两个专名要用两条专名线，中间的断开要能够辨认；此时不能用一条专名线连起来标注，否则连续的两个专名会被误认为是一个专名。

Interlinear punctuation should be as close to the marked text as possible.
The thickness and size of the interlines and emphasis dots is determined by the font design and typesetting rendering engine, but even though there is no absolute limitation, the sizing of these punctuation marks should be harmonious with the font size and letter-spacing of the marked text.
行间标点应尽量紧贴所标注汉字一侧。
行间线、着重号的大小或粗度取决于字体和排版引擎的设计，虽然没有绝对限制，但显然尺寸上应与所标汉字字号、字距相匹配。

3. For loose setting or situations when letter-spacing needs to be increased
    1. If the letter-spacing of the marked text needs to be increased, the length of the interline should be increased to match without being broken
    2. In accordance to what was explained in the first general guidance, even after the letter-spacing is increased,  Emphasis Dots must continue to be center-aligned with the text they are marking
3. 在疏排或行内调整需要拉开字距的情况
    1. 如果被标注字的字距被拉开，行间线应相应延长且不能断开
    3. 根据上述通则 1. 拉开字距后，着重号依旧应与字符居中对齐而不能错位。
