Question 1

What is the difference between full-width and half-width characters?

Accepted Answer

Full-width characters take up the space of two half-width characters. Full-width is commonly used in CJK (Chinese, Japanese, Korean) text for consistent spacing, while half-width is standard for ASCII/Latin characters. For example: 'Ａ' is full-width and 'A' is half-width.

Question 2

When should I use full-width characters?

Accepted Answer

Use full-width characters when writing formal CJK documents, creating text that needs consistent character spacing, or when specific systems require full-width input. Many Japanese and Chinese documents traditionally use full-width punctuation and numbers.

Question 3

When should I use half-width characters?

Accepted Answer

Use half-width for programming, web development, email addresses, URLs, and when mixing with English text. Half-width characters are also more efficient for storage and display on non-CJK systems.
