Support utf-8 title

[idealclover]

Hi so glad to find this program! :)
I'm now using obsidian.md instead of roam. When trying to import from notes, problems were found.
I'm Chinese so my notes are named in Chinese. But the links containing Chinese could not open correctly. However, the reference links could be opened. Hope that this issue can be solved~
Another issue is that when an article has no title, there will be no title showed in web page, maybe the name of this file could be show here?
Thanks a lot!

@idealclover In node_modules/gatsby-remark-double-brackets-link/lib/index.js, change ${slugify_1.default(title)}. The slugify plugin here will swallow chinese character. Find a plugin that supports your language, or if all file names do not contain special characters like SPACE simply replace it with ${title}.

Now you can jump to the right page. But it's not opened on the right side. This is because chinese in URI cannot match the local file name. To solve it, change withPrefix(x.slug) === withPrefix(href) to withPrefix(x.slug) === withPrefix(decodeURI(href)) in node_modules/gatsby-theme-garden/src/components/mdx-components/anchor-tag.js.

Now everything should work well.

Happy to merge a PR if you found a slugify function that support chinese characters

In https://roam.garden/ fork I resolved this by using a custom slugify wrapper that returns a sha1 hash of original title if the output of slugify is empty
