This looks very promising, I'm impressed by the work you guys have done (big
thumbs up).
There are a few issues/questions I have after reading your document:
"Therefore, command such as 'print' and 'echo' automatically convert their
arguments to the specified encoding. No automatic output encoding is
performed for anything else."
What about the other functions that output to stdout directly, such as
readfile() and passthru()?
"The conversion failure behavior can be customized"...
Maybe it would be a nice feature to have an U_INVALID_EXCEPTION, so that
users can actually catch the error and deal with it. Just an idea. Of course
it's not usual for the PHP core and extensions to throw exceptions, but
perhaps this could change with PHP6.
"In order to create binary string literals, a new syntax is necessary:
prefixing a string literal with letter 'b' creates a binary string."
The b-prefix for binary strings is great, but how does that work with a
function like file_get_contents() or fread() ?
One can't do: $data = bfile_get_contents("somefile.bin");
And even if one could (somehow), wouldn't file_get_contents() already
unicode-encode all data it reads? How does such a function know if the user
is expecting binary or textual data or does the encoding simply happen after
the string is returned? In that case it's up to the user to use the
b-prefix, but then there's the syntax problem I mentioned.
Keep up the good work,
Ron
