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 Oct 19 '15 at 10:58
  • @Wrzlprmft my question here is , any given webfont, is there a way to see the unicode ranges it covered? – Mohamed Hussain Oct 19 '15 at 13:11

    I understand that. I am just doubting that this is really what you want. – Wrzlprmft Oct 19 '15 at 13:14

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. – cherouvim Aug 16 '20 at 6:06
  • The two numbers at the end show this though. 1/95 means it contains 1 out of 95 characters in that range. – thomasrutter Aug 16 '20 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. – cherouvim Aug 16 '20 at 18:13
