Who builds GlyphCopy
GlyphCopy is operated by Netwiz Inc. (Tokyo, Japan). We design, build, and maintain the site as a long-term resource. The same team is responsible for editorial decisions, the conversion logic, and the privacy posture described in our policy.
If you spot a mistake or have a feature request, write to info@netwiz.co.jp — every email is read by a person on the maintenance team.
How the tools work
Every conversion, generation, and detection runs in your browser using JavaScript. Nothing you type or paste leaves your device. There is no account system, no upload endpoint, and no server-side text storage.
The conversion logic is implemented as plain TypeScript modules. Each transformation maps input characters to specific Unicode code points, and the table of code points is maintained alongside the article copy so that the tool, the documentation, and the FAQ stay consistent.
Our data sources
We rely on the Unicode Standard for character properties, Unicode Code Charts for the canonical glyph reference, the Unicode Character Database (UCD) for category and bidirectional class data, and the WHATWG HTML specification for input-validation behavior. We do not invent code points or assign meanings outside of the official standard.
- Unicode Standard: https://www.unicode.org/standard/standard.html
- Unicode Code Charts: https://www.unicode.org/charts/
- Unicode Character Database (UCD): https://www.unicode.org/ucd/
- Unicode UAX #15: Normalization Forms: https://www.unicode.org/reports/tr15/
- WHATWG HTML — Input forms: https://html.spec.whatwg.org/multipage/input.html
Editorial principles
We do not exaggerate compatibility. When a platform may strip a character, we say so. We avoid promises like 'guaranteed to work in Free Fire' or 'bypass username rules' because Unicode handling on third-party platforms changes frequently and is outside our control.
We do not promote impersonation, spam, or moderation evasion. Our copy is written for layout, accessibility, design testing, developer debugging, and personal expression.
Update cadence
Articles carry a 'Last reviewed' date that is set per-page in the source data. We update that date only when the underlying content actually changes. The sitemap reflects the same dates so search engines see meaningful lastmod values rather than build timestamps.
Accessibility
Every interactive element has a label, every copy event is announced via aria-live, and every focusable element shows a visible focus ring. Contrast ratios meet WCAG AA on the default Apple-style light theme. Screen-reader behavior is one of the criteria we use when grading fancy text styles in the comparison table.
