[GitHub] [echarts] Wetterquarz opened a new issue, #18583: [Bug] Zrender Overflow Word Wrapping can Break Apart Characters and can Break Before Spaces
Wetterquarz opened a new issue, #18583:
URL: https://github.com/apache/echarts/issues/18583
### Version
5.4.2
### Link to Minimal Reproduction
https://echarts.apache.org/examples/en/editor.html?c=line-marker&code=PYBwLglsB2AEC8sDeAoWtJgDYFMBcya6GOAHmAQOQAqOAtiDgE4CGYArkzrAMIAWLaAHNuEOGD7cewOmKGwA6jhwBrADSxBAE02wsMeWDJgMkriwBmRphmCwLwJgGNuAd1YgQc27AGeccK4QEpqAPBuAhjsRUZEx0ZRqROhG5ADKYACeuASoxMTAAG7MFvquVABG5irxicRBWhIEACwADABMNQC-RB0JHQDcQA
### Steps to Reproduce
1. Create a chart with any text and set it up to wrap set text when overflowing.
2. Use characters of the so-called non-BMP.
3. Try some widths until you break within the character or before a space (or both as in the minimal reproduction)
### Current Behavior
The 3rd line starts with a space.
The 3rd line doesn't calculate the character widths correctly and is short.
One of the Domino Tiles has been broken into two illegal characters.
### Expected Behavior
According to the Unicode Standard (https://www.unicode.org/reports/tr14/#SP) the wrapping should occur after all space-characters when a line-break is desired by the algorithm. Characters should also, obviously, not be broken in two and their width should be correctly determined.
### Environment
```markdown
- OS: Windows 10
- Browser: Edge 112.0.1722.58 (Chromium)
```
