Quick Reference

Universal Text Rules

Encoding

• Always verify encoding first: file -bi document.txt
• Normalize line endings: tr -d '\r'
• Remove BOM if present: sed -i '1s/^\xEF\xBB\xBF//'

Whitespace

• Collapse multiple spaces: sed 's/[[:space:]]\+/ /g'
• Trim leading/trailing: sed 's/^[[:space:]]*//;s/[[:space:]]*$//'

Common Traps

• Smart quotes (" ") break parsers → normalize to "
• Em/en dashes (– —) break ASCII → normalize to -
• Zero-width chars invisible but break comparisons → strip them
• String length ≠ byte length in UTF-8 ("café" = 4 chars, 5 bytes)

Format Detection

# Detect encoding
file -I document.txt

# Detect line endings
cat -A document.txt | head -1
# ^M at end = Windows (CRLF)
# No ^M = Unix (LF)

# Detect delimiter (CSV/TSV)
head -1 file | tr -cd ',;\t|' | wc -c

Quick Transformations

Before Processing Checklist

• [ ] Encoding verified (UTF-8?)
• [ ] Line endings normalized
• [ ] Delimiter identified (for structured text)
• [ ] Target format/style defined
• [ ] Edge cases considered (empty, Unicode, special chars)

这个 Skill 质量不错，涵盖了写作、清洗数据、写营销文案、学术引用和翻译等多个实用场景。规则写得很清晰，可以直接照着做，对日常文字处理工作很有帮助。美中不足的是没有独立的使用说明，各部分内容之间的关联不够明显，部分例子也可以更丰富。总体来说值得推荐，质量可靠。
