Would the following be a correct way to determine whether there's a problem? * First call setlocale(LC_CTYPE, "en_US.UTF-8") * Next feed the UTF-8 string representation of every Unicode codepoint one at a time to mbstowcs() a

What does the presence or absence of __STDC_ISO_10646__ indicate exactly? I found this part of the C99 spec obscure. For instance, the macOS clang environment does not define this symbol. Is their implementation of wchar_t or <wctype.h&g

OP has an extravagant threat model. Yeah if I were trying to hide communications from some dictator where even the metadata of recipient and timestamp is damning then of course email is out. PGP is a good way to communicate under the right

Even supposing they beat the GNU wc, that's not too hard... try beating this one: https://github.com/begriffs/wc I wrote it in reply to an earlier post, where someone "beat C" with Haskell.

Although I use a mac for work, I have a spare thinkpad with openbsd, which I think of as my "forever system." I put stable software on it and generally go with the OS defaults. Over time I patiently refine the configuration files,

Vim can also edit remote files, with its built-in netrw module. It can do ssh, ftp, dav, fetch, http, rcp, rsync. vim scp://remoteuser@server.tld//absolute/path/to/document :help netrw-start

Yes, this is a good idea, although I'd like to note there is more nuance. * `encoding` is what vim uses internally -- the way buffers and registers are stored in memory. Default value is latin1 as you mention, but it will also pick up

Thanks for the correction, can you give me a more precise date for nvi? I can update the article.

Sorry, the way I phrased that was sloppy. I should have said, "main author abandoned, saying NeoBundle ripped off code." http://www.gmarik.info/blog/2014/why-i-stopped-contributing-...

Rather: don't presume anything, read the language specification for the version you are writing (C89, C99, etc). "Measuring" is exactly the wrong thing to do because often it is indicative of only your specific architecture&#

Your article mentions: > Unicode is pretty established, some use it with the wchar_t API in POSIX, some more as non-POSIX via external non-standardized utf-8 libraries Just wanted to note that wchar_t is not POSIX per se, but comes from

As it says in the article: > The examples in this article conform to the C89 standard, but we specify C99 in the Makefile because the ICU header files use C99-style (//) comments.
