(?< = .)(?=.$)
或者匹配单个字符，然后在替换中使用完全匹配的字符，后跟“-”。
. (?=.$)
英文:
You are almost there, but you have to assert a character followed by the end of the string.
In the replacement use -
(?<=.)(?=.$)
Or match the single character and only use the lookahead. Then use the full match followed by - in the replacement.
.(?=.$)
