I ran into this problem recently on one of our blog posts: we used some Claude output which included tables drawn with Unicode line drawing characters. However, our monospace font did not include these characters, and so rendering fell back to another font in our font stack with different width metrics. I fixed it by using a font that had similar metrics and did include those characters with `unicode-range` (to only select characters we needed) and `size-adjust` (to match font width more exactly), and adding it to the stack. It's a little hacky but works pretty well in practice.

Claude Code with Opus 4.8 is also bad at aligning boxes with content in French (with accentuated letters such as "é" which are multibyte in UTF-8).
