How to font inspector

Drop in a TTF, OTF, WOFF or WOFF2 file.
Browse the glyph grid, check the Unicode ranges, and read the embedded metadata.
Use the preview text field to test how the font handles specific characters.

About this tool

Font files carry more metadata than most people expect. Beyond the shapes of the characters, a font embeds typographic metrics — cap height, x-height, ascender and descender values, kerning pairs — that determine how text flows on a page. Variable fonts add a full axis specification: weight, width, optical size and any custom axes the designer chose.

The Unicode coverage tables are particularly useful for multilingual work. A font can claim to cover "Latin Extended" while missing half the diacritical marks needed for Vietnamese, or claim "CJK" while containing only the most common 2,000 of the roughly 20,000 characters in the block. Checking the actual glyph coverage before choosing a font for a project saves discovering the gap after the design is finished.

Questions

What information does a font file contain?

Beyond the glyphs themselves, a font typically embeds the designer's name and foundry, a copyright notice, a licence identifier, version number, PostScript name, supported Unicode ranges broken down by block, and spacing tables (kern pairs, advance widths, side bearings). Variable fonts also carry axis definitions and named instances.

How do I check whether a font covers a particular language?

The Unicode coverage table lists which Unicode blocks the font provides glyphs for — Latin, Cyrillic, Greek, Arabic, CJK Unified Ideographs and so on. The glyph grid lets you search or browse by block. Paste a sentence in your target language into the preview field to see missing glyphs rendered as squares.

Where is the licence information?

Font licences are embedded in the name table. The inspector surfaces both the short licence identifier (often something like "This font software is licensed under the SIL Open Font License") and any longer description field. This is the right place to check before embedding a font in a PDF or using it commercially.
