It turns out that Unicode support in Terminals is a lot more difficult than it first appears. A quick overview of special support for Unicode characters in Terminals:

• "Wide" or "Fullwidth" characters, particularly for East Asian languages and emojis, are codepoints that occupy two cells in a terminal instead of one.
• "Zero" width combining characters used in languages such as Arabic, Hebrew, or Hindi do not occupy any cells themselves; instead, they modify the previous character.
• "Zero Width Joiner" (ZWJ U+200D) reduces and combines many codepoints into a single emoji. This is similar to combining, but encoded in a completely different way.
• "Variation Selector-16" (VS-16 U+FE0F) is a special character that, for specific "Narrow" emojis consuming one cell, causes them to become "Wide", consuming two cells.

Tinboard is a client for Pinboard, based in the terminal, it includes:

• Add/edit/delete bookmarks.
• Various forms of filtering.
• Filtering with tags.
• Full text search.

Also includes the rather hilarious comment "I wish there were more full blown app examples out there", back when Textual was pretty damn new and barely out of the initial "CSS branch" release.

I don't agree with much of this, but I recognise it's a valid position. To quote from the TL;DR at the end:

"Capping dependencies has long term negative effects, especially for libraries, and should never be taken lightly. A library is not installed in isolation; it has to live with other libraries in a shared environment. Only add a cap if a dependency is known to be incompatible or there is a high (>75%) chance of it being incompatible in its next release. Do not cap by default - capping dependencies makes your software incompatible with other libraries that also have strict lower limits on dependencies, and limits future fixes. Anyone can fix a missing cap, but users cannot fix an over restrictive cap causing solver errors. It also encourages hiding issues until they become harder to fix, it does not scale to larger systems, it limits your ability to access security and bugfix updates, and some tools (Poetry) force these bad decisions on your downstream users if you make them. Never cap Python, it is fundamentally broken at the moment. Also, even packing capping has negative consequences that can produce unexpected solves."
