how to search for Unicode character using vim character class and reoder their position-CodePudding

Given

数据     Data
子树      subtree

Desired output

Data  数据
subtree 子树

For non unicode, this can be achieved using command s/\(\w\ \) \ \(\w\ \)/\2 \1/g

CodePudding user response：

The following collection includes all "word characters" as matched by \w as well as all characters in the CJK Unified Ideographs Unicode block:

[0-9A-Za-z\u4E00-\u9FFF]

See :help collection.

It can be used as-is in place of \w in your pattern:

:%s/\([0-9A-Za-z\u4E00-\u9FFF]\ \) \ \([0-9A-Za-z\u4E00-\u9FFF]\ \)/\2 \1

That specific range (largely) covers the characters you provided in your sample. You may have to adjust it if your real world requirements are different.
