Unicode characters were rendering wrong in PDFs. Claude Code raced through several approaches in an afternoon to find each one's limits, ending in a custom font fallback. Then a day of polish.

Debugged PDF rendering issue with Unicode characters; iterated through multiple potential approaches with Claude’s help; implemented custom font fallback system.
Took about a day of tweaking/testing/cleaning after initial work; Claude’s rapid iteration through approaches was valuable.
I'm getting Unicode character rendering issues in PDFs with [library]. The issue: [describe problem]. Suggest multiple approaches to solve this: font fallback systems, character encoding fixes, library alternatives. For each approach, show sample code. I'll iterate through them.
