Why does trimming fail in some systems?
Different runtimes and libraries treat Unicode whitespace classes differently.
Whitespace Characters
Unicode includes many whitespace characters that look similar but behave differently across tools.
Quick checks
- Spot tabs, NBSP, narrow NBSP, and ideographic spaces.
- Fix mismatches in search, split, and deduplication.
- Normalize whitespace before indexing and export.

FAQ
Is replacing all whitespace with plain space safe?
Not always. Some contexts require preserved line breaks or tabs for readability and semantics.
When should I normalize whitespace?
Normalize at ingestion boundaries, then keep a predictable internal format across your pipeline.
