Ok, issue sorted - for now anyway - helps to get some rest, and then
consider alternatives to a problem...<smile>
function morphString($sIn) {
$sOut = "";
for ($I = 0; $I < strlen($sIn); $I++) {
$sChr = $sIn[$I];
if (ord($sChr) >= 10 && ord($sChr) <= 126) {
$sOut .= chr(ord($sChr));
}
}//end of looping
return $sOut;
}//end of morphString function
I basically typed in a sort of test string including all keyboard characters
I would want to allow/include, including things like \\ \" \n \r etc., as
well as all capital letters, all punctuation marks, etc., and ran it through
another looping function to determine max and min values for the ord()
function on each character, and thus determined that anything ranging from
10 to 126 could be included, etc.
Stay well

Subject: Re: Characters in an uploaded text file being corrupted
Thanks - will check that out, but only issue is that this will need
end-users to try sort something like this out, and they won't necessarily
be the most technical types as such, and, I also wouldn't have too much
control over what they'd originally used to generate the content.
Am thinking that might be able to handle character set encoding processing
a bit more simply using python, which is currently my other primary
programming language, so might try out something like creating a bit of a
cross platform utility app that they can try use initially to control
something like this before uploading content, but, let's see...

Do not use Microsoft Word to save files that need to be read-in by other
software. Ever. It *always* finds a way to screw it up. Even if you cut
and
paste it into the other program, I've heard cases where Word has put
unprintable control characters into the pasted output, that showed-up as
spaces in the form, then corrupted the output at runtime.
I suggest you open the saved file in NetBeans. In the NetBeans
settings dialogue, enable the options to "show control characters" and
"process file as unicode" (iirc). That will cause NetBeans to display
all
characters your font set contains, display a square box for the ones it
doesn't, and display the various icons for control characters.
If column alignment in your file is important (for example a set number
of
spaces between tokens and operators), you should be using a monospace
font.
The best one I've ever used is available here:
http://code.google.com/p/buddypress-media/downloads/detail?name=ttf-bitstream-vera-1.10.zip
It's also really easy to read.
For text streams in production site, take a look at BP-Media's sanitizer
classes. Unicode to ASCII to HTML entity conversion is a tricky business,
and these functions will ensure you get the right kind of output no
matter
what users throw at you. For example, people embedding unicode sequences
in
an ASCII stream.

Ok, specifically told that storage field to make use of UTF8_unicode_ci,

Suppose might try something like copying/pasting from text file in
notepad, into something like a textarea field, but, don't think that
would
always be the perfect process in this site.
Will try a couple of other options with regard to DB encoding, and see
if
come right, but, let's see...

Hi
Ok, and, FWIW, this test text file is a word document that have saved
as
a
text file, and when now resaved it using specifically unicode
encoding,
it
seemd to eliminate this issue,
Make sure the MySQL Db, table, field are correctly set for the
encoding.
MySQL does not default to UTF-8 so you have to manually set it when
creating the Db/table. IIRC, newer versions can also have the encoding
set per field.
but would have thought there might be a
relatively simple way to handle something like encoding conversion in
PHP
itself..?
PHP cannot read minds, unfortunately. There are ways to handle encoding
conversions, but I don't think anyone would call them 'simple'. ;-)
See the Multibyte String extension for one way.
