17  * Sequences can be found at
18  * http://www.fileformat.info/info/unicode/
19  * http://www.utf8-chartable.de/
20  * and other places
21  *
22  * Please be conservative when adding code points below. While many modern
23  * systems default to UTF-8 and handle it well, some do not. The Windows
24  * console is a notable example. As a general rule you probably shouldn't
25  * stray too far from code page 437 or WGL4:
26  * https://en.wikipedia.org/wiki/Code_page_437
27  * https://en.wikipedia.org/wiki/Windows_Glyph_List_4
28  *
29  * Hopefully we can dispense with the sequences below and simply encode our
30  * files as UTF 8 at some point. For example gcc has supported UTF 8 since
31  * at least 3.4. Visual C++ on the other hand is much more problematic.
32  * 2015 and later support /source-charset:utf-8, but prior versions appear
33  * to require a UTF 8 BOM.
