How can I find out what Unicode ranges a webfont file (may be WOFF2, WOFF, TTF or EOT) covers?

For example I am analysing a latin font, is it possible to know what are the Unicode ranges of latin covered by it? Is there any tool available to analyze it?

    Just a sidenote: With the latin blocks, it’s much more important which characters are covered than which characters aren’t. Except for Basic Latin, each of the Latin ranges contains at least one character that is deprecated or only for very exceptional uses (e.g., ¦ʼnDZⱶꝚẜ). E.g., there is no reason for a font to fully cover Latin-1 Supplement, except for its own sake.

  • @Wrzlprmft my question here is , any given webfont, is there a way to see the unicode ranges it covered? Oct 19, 2015 at 13:11

    I understand that. I am just doubting that this is really what you want.

You could install FontForge - it's a free and open source font editor and will show you what glyphs the font has - it has various ways of laying out the code points in order.

Note that coverage isn't as easy as looking at which blocks are fully covered. For example, it's very common for a font to contain basically all of Latin-1 plus a small handful of characters from Latin-Extended-A/B in order to fully support languages like French, Hungarian, Catalan etc, see this table. You do NOT need most of Latin-Extended-A/B to cover most European languages, but you DO need more than what's in Latin-1 for many.

  • Unfortunately this simply displays ranges in which at least one glyph exists. For example, for a font file with just "A" in, FontForge will display Basic Latin U+0020-U+007E 1/95.

  • The two numbers at the end show this though. 1/95 means it contains 1 out of 95 characters in that range. Aug 16, 2020 at 13:20
  • @thumasrutter: Yes but it doesn't help me. It just says that the 20-7E range (95 possible glyphs) has only got 1 in there.

There's a neat feature now in FontForge (see @thomasrutter's answer) that lets you visually see all the glyphs in a given range, which helps when determining which unicode ranges that your font supports.

After opening the font with FontForge, click Element > Font Info... > Unicode Ranges. This will give you an overview of how many glyphs exist in a given range. For example, for me it says

Basic Latin  U+0020-U+007E 95/95
General Punctuation  U+2000-U+206F 85/111

meaning that I have all of the glyphs in Basic Latin (95/95) but only 85 out of the 111 glyphs in General Punctuation.

Now, to see which 85 glyphs, click the "General Punctuation" entry in the list. This should make your other window jump to and highlight them as seen in the image below.

With this, it's easy to click the individual glyphs and figure out what ranges your font supports. In my case, it's U+2000-200B, U+2010-2027, and U+202F-205F in General Punctuation.

You would then have to do this for each of the ranges in the list.
