Re: How do you print all Unicode characters in a range - I want the subscripts, can't google a range of Unicode.

You can either write to a function instead and load it in a text editor aaargh not to a "function" i meant to a "file". like auto f = File("test.txt", "wt"); f.writeln(s); then open test.txt and make sure it is opened in utf-8 mode.

You can either write to a function instead and load it in a text editor, or use a non-broken writeln like my terminal.d's ``` void main() { // using the same string... dstring s = ""; for (dchar i='ₐ'; i < 'ₜ'; i++) s ~= i; // this will output correctly import arsd.terminal; auto terminal = Terminal(ConsoleOutputMode.linear); terminal.writeln(s); // this will not import std.stdio; writeln(s); } ``` Screenshot output: http://arsdnet.net/dcode/writelnsux.png Now, while it outputs correctly, you'll still note a bunch of empty boxes. That's because the *font* I'm using doesn't include those characters. If you changed fonts there's a decent chance you can see those too.

The output will be bad because of Windows specific behavior related to not outputting as UTF-16. This will print all the characters in the block "Superscripts and Subscripts". The Unicode database is very out of date (just waiting for merge for update), but should be ok for this example. ``` import std.uni : unicode; import std.stdio : writefln; void main() { foreach(c; unicode.InSuperscriptsandSubscripts.byCodepoint) writefln!"U+%X = "(c, c); } ``` Unfortunately I'm not seeing an obvious way of determining subscript/superscript from what we have. You can do it with the help of[0] via Super/Sub field values, which originate from UnicodeData.txt's Decomposition_Type field, but you shouldn't parse that if you only want just this one set of values.
