Question 1

How are Chinese characters and English words counted in this tool?

Accepted Answer

We use industry-standard multilingual tokenization algorithms:

① Chinese Character Count:
Matches Unicode CJK Unified Ideographs (`\u4e00-\u9fa5`), counting each distinct Chinese character individually.

② English Word Count:
Matches continuous alphanumeric sequences and hyphenated words (`\b[a-zA-Z0-9_-]+\b`) as standalone words, unaffected by irregular spacing.

Question 2

What is the difference between "Total Characters" and "Excluding Spaces"?

Accepted Answer

Their counting scopes and usage conventions differ:

① Total Characters:
Includes letters, digits, punctuation marks, newline breaks (`
`), and all spaces.

② Excluding Spaces:
Strips ASCII spaces, full-width spaces, tab indents, and newlines. Many essay submissions, character-limited publishing rates, and social media constraints (Twitter/Threads) rely strictly on character counts excluding spaces.

Question 3

How do the case conversion functions (UPPERCASE, lowercase, Title Case) operate?

Accepted Answer

Supports standard letter case transformations:

① UPPERCASE:
Converts all letters to capital form (e.g. `hello world` → `HELLO WORLD`).

② lowercase:
Converts all letters to small form.

③ Title Case:
Capitalizes the first letter of each word and lowers remaining letters (e.g. `hello world` → `Hello World`), ideal for headline typesetting.

Question 4

Does "Remove Duplicate Lines" preserve the original line ordering?

Accepted Answer

Yes, original sequence is strictly maintained:

① Stable Order Preservation:
Using a Set-based deduplication filter, only subsequent redundant duplicates are removed, preserving the first appearance of each unique line.

② Best Use Cases:
Ideal for cleaning up mailing lists, phone rosters, keyword sets, and raw database exports.

Question 5

Is there any privacy or data leakage risk when pasting sensitive text into this tool?

Accepted Answer

Zero Risk! This tool operates entirely client-side inside your local browser memory:

① Zero Backend Transmission:
All character statistics, case transformations, and cleanups execute in your local JavaScript runtime.

② Zero Cloud Logging:
No text is ever dispatched to or stored on remote servers. Works fully offline.

Question 6

How do "Remove Empty Lines" and "Trim Line Spaces" help with data cleansing?

Accepted Answer

Efficient preprocessing utilities:

① Remove Empty Lines:
Eliminates blank lines and lines containing only whitespace, condensing document layout.

② Trim Line Spaces:
Strips leading and trailing spaces from every line, cleaning up artifacts copied from PDFs or web tables before importing into Excel or databases.

Question 7

Can this text utility handle very long manuscripts or large datasets (100,000+ words)?

Accepted Answer

Yes! Optimized with high-efficiency regular expressions and native JavaScript string APIs, the tool processes manuscripts exceeding 500,000 words in just a few milliseconds.
