I want to display the compound letter ̤̫ 」 so that it can be seen on the rabbit's face.

The characters you include in the title (make sure the links in the body are not supplementary information so that the question makes sense without looking at the link) are a combination of three Unicode code values:

U+164F CANADIAN SYLLABICS CARRIER SO

U+0324 COMBINING DIAERESIS BELOW

U+032B COMBINING INVERTED DOUBLE ARCH BELOW

As I know that you may not be able to read due to environmental dependence, it would have been better to write the character code in the body of the question (at least to the person who checked the source).

̤̫ <
↑
ᙏ̤̫

How these non-standard composite characters are drawn is entirely environmentally dependent, and there may be three tofu lines, such as the Mac version of Chrome, or there may be three unsynthesized characters next to each other.

If you really want to use three characters to display emoji-style characters (environmentally independent), you will have to write them as separate characters without using composite characters and then use CSS to intentionally overlap them.

span.first{
    display:inline-block;
    position:relative;
    top:0;
    left:0;
    width: 1.2em;
    height —1.5em;
    text-align:center;
    vertical-align:baseline;
  }
  span.second {
    display:inline-block;
    position:relative;
    top —0.8em;
    margin-left: -1.2em;
    width: 1.2em;
    text-align:center;
    vertical-align:baseline;
  }
  span.third {
    display:inline-block;
    position:relative;
    font-size: 50%;
    margin-left: -2.4em;
    top:1em;
    width: 2.4em;
    text-align:center;
    vertical-align:baseline;
  }

<span class="first">#x164F;</span class="second">#x00A8;</span class="third">#x23;#x23;print>

(There seems to be a better way to do this, but the intention of writing this is to say, "You don't want to go this far, do you?")

In short, it's the same logic that some of the emojis that can be typed and displayed normally on Mac and iOS cannot be displayed on Windows.The reason Safari and Chrome work differently on the same Mac may be because HTML rendering doesn't use the entire regular text drawing engine, so it's only browser-specific (because Chrome seems to be throwing a whole text display at the system).

If you want to make it environmentally independent, remember that composite characters are useless.
