CJK word can not be linked

[xcodebuild]

Describe the bug
CJK word without space can not be linked.

To Reproduce
Steps to reproduce the behavior:

1. Create a note with a CJK word: 测试.md
2. Create another note with this word, for example content 这是一段测试内容
3. Scan Vault
4. 测试 won't be linked auto.
5. But if we add space between this CJK word with other content, for example 这是一段 测试 内容, it will be linked as expected.

Close because link all CJK words without space is quite an unsafe behavior.
