Chinese Script Converter

Simplified and Traditional Chinese are writing conventions, not two interchangeable alphabets. Many characters have direct counterparts, yet publishing for Taiwan or Hong Kong also involves regional word choices. A character-only replacement can therefore produce readable text that still sounds wrong for its intended audience.

Standard script conversion changes character forms without deliberately localizing every phrase. Regional phrase conversion goes further. It can turn software terminology such as 软件 into Taiwan usage such as 軟體, or choose a Hong Kong form where the local convention differs. That distinction matters in user interfaces, documentation, subtitles, product copy, and other text where regional vocabulary carries as much weight as glyph shape.

• Use Standard Traditional when the task is general script conversion and regional terminology is not the target.
• Use the Taiwan phrase profile for Taiwan publishing, then review names, house style, and specialist terms.
• Use the Hong Kong phrase profile for Hong Kong publishing, with extra care where phrase coverage is incomplete or context-dependent.
• Use the matching regional reverse profile for Simplified output, while expecting that the original wording may not be reconstructed exactly.

Phrase-aware conversion prefers the longest dictionary match it can apply at a position. This protects known multi-character terms from being split into unrelated character substitutions, but a dictionary cannot infer every meaning from context. Proper names, quotations, classical text, newly coined terms, and domain-specific vocabulary deserve a human pass.

Conversion is also not guaranteed to be reversible. Several source forms can map to one target form, and a regional phrase may be replaced with a different expression rather than a one-character counterpart. Keep the source text and compare the converted copy before publication.

How to Use This Tool:

Choose the destination convention first, then review changed wording rather than treating conversion as automatic translation.

1. Select a Conversion profile. Use the standard profile for script conversion, or choose Taiwan or Hong Kong phrases when the audience expects regional vocabulary.
2. Paste up to 10,000 Unicode characters into Chinese source text. The text must contain at least one Han character; Latin text, punctuation, line breaks, and markup-like text remain ordinary text.
3. Leave Normalize line endings off unless the destination requires line-feed separators. Enabling it changes CRLF and lone carriage returns to LF before conversion.
4. Read the converted text beside the change counts. A zero-change result can mean the source already matches the profile, or that no dictionary entry applied.
5. Copy or download the result only after checking names, technical terms, quotations, and audience-specific wording against the source.

Interpreting Results:

Changed positions counts aligned Unicode positions whose source and output code points differ. It is a review aid, not a linguistic accuracy score. Phrase replacement can change text length, so later positions may also count as changed after an insertion or deletion shifts the alignment.

Changed means the final text is not identical to the normalized source. When line-ending normalization is enabled, the result can be marked changed even if every Chinese character remains the same. Check the profile label and normalization status before attributing every difference to script conversion.

A fluent-looking result can still contain the wrong term for a product, person, place, legal name, or specialist field. Compare critical copy with an approved terminology list or ask a qualified editor for the target region.

Technical Details:

Chinese conversion operates on Unicode text using a version-pinned OpenCC dictionary set. The shipped data combines character mappings with phrase dictionaries and region-specific variants. Text that does not match a dictionary segment passes through unchanged.

Transformation Core:

Worked Transform:

The source phrase 软件和服务器 becomes 軟件和服務器 under Standard Traditional. The Taiwan phrase profile produces 軟體和伺服器, while the Hong Kong phrase profile produces 軟件和伺服器. The different results show why script conversion and regional terminology are separate decisions.

The source sequence is optionally normalized from CRLF or CR line endings to LF, segmented for phrase matches, passed through the selected conversion chain, and then compared with the normalized source by Unicode code point. Counting code points avoids treating a supplementary character as two UTF-16 code units.

Rule Core:

• Input must contain non-whitespace text and at least one Han character.
• The maximum input is 10,000 Unicode code points, not 10,000 bytes.
• Non-Chinese text remains inert unless it forms part of a dictionary phrase.
• The dictionary and profile behavior are pinned to OpenCC and opencc-js data version 1.4.1 for repeatable results.
• Reverse conversion uses the matching reverse profile, but many-to-one mappings prevent a general round-trip guarantee.

Accuracy and Privacy Notes:

The dictionaries provide deterministic conversion, not translation, proofreading, or a guarantee of regional editorial quality. The OpenCC project identifies some Hong Kong phrase profiles as having incomplete phrase coverage, so high-stakes publishing needs human review.
