Thanks for your pull request.

However since this is merely a fork of open-i18n/rust-unic, I'd suggest you to send pull requests to the orignial repo.

Also I see you are merging into ucd/unihan, if you have any suggestions to the existing implementation I will be more than happy to discuss it in open-i18n#225. Also as we have disucssed in open-i18n#255, the current implementation is waiting for a refactor of how rust-unic does Unicode character database parsing (which would likely affect the current implementation of Unihan data parsing quite heavily).

谢谢你的理解。

目前为止，考虑到 ucd/unihan 的具体实现还未出现，所以我并没有什么建议。

我尝试合并你的 PR 分支是因为这个 PR 似乎停滞了相当长的一段时间，所以我打算先使用下你当前的分支。考虑到我个人一直是在 Nightly 版本里工作的，所以出现了一些模块路径问题。

我会持续关注该 PR 的进度。

谢谢你所做的工作。

So far, I don't have any suggestions considering that the implementation of ucd/unihan has not yet appeared. I'm trying to merge your PR branch because this PR seems to have stalled for quite a while, so I'm going to use your current branch first.

Given that I personally have been working in the Nightly version, there have been some module path problems.

I will continue to pay attention to the progress of the PR. Thank you for the work you have done.
