为什么Emoji表情无法在Chrome中显示超过特定大小? [英] Why do emoji not render above a certain size in Chrome?
问题描述
由于某种原因，表情符号在Chrome中无法呈现超过特定大小的图像.这个大小似乎与font-size或scale无关，只是被渲染的表情符号的像素大小.
For some reason emoji do not render above a certain size in Chrome. This size seems unrelated to font-size or scale, it is just simply the pixel size of the emoji being rendered.
由于图像不是矢量，我可以理解不希望它们过大的原因，但是我不确定这只会影响Chrome.
Since the images are not vectors, I can understand the reasoning behind not wanting them to be abnormally large, however since this only effects Chrome I am unsure.
这是Chrome浏览器错误，还是emoji标准中指定最大预期大小的内容?
Is this a Chrome bug, or something in the emoji standard that specifies a max intended size?
以下是两个非渲染表情符号的示例:

推荐答案
这是一个Chrome错误
Is this a Chrome bug
是的.例如，请参阅以下内容:
Yes, it is. See, for example, these:
- 错误报告: https://bugs.chromium.org/p/chromium/issues/detail?id = 719648
- 错误报告: https://bugs.chromium.org/p/chromium/issues/detail?id = 501071

根据大量测试，当前表情符号的最大字体大小为54px.但我不会放弃希望:)
Based on a lot of testing, 54px is the current maximum font size for emoji. But I will not give up hope :)
2018年10月更新:
Update October 2018:
在Mobile Chrome 69中，表情符号的最大字体大小为146px.
The maximum font-size for emoji in Mobile Chrome 69 is 146px.
如果将其设置为147px，则表情符号无法正确呈现: https://app.crossbrowsertesting.com/public/ib8393c20a124bac/livetests/14400384/snapshots/za103323111cb78aeff2
If you set it to 147px, the emoji are not rendered properly: https://app.crossbrowsertesting.com/public/ib8393c20a124bac/livetests/14400384/snapshots/za103323111cb78aeff2
