Thanks Rasmus! Honestly, that is REALLY helpful! I was just coming back here to post that I had found that very same answer. But I am glad to hear it confirmed by the experts. Bottom line: I was just being silly/ignorant. I went and downloaded a simple HEX editor and compared the actual binary output of several files that I had created using both PHP, and my favorite text editor (emeditor from emeditor.com). I then realized what probably everyone else here already knew: that (most of the time) the actual binary output from "Windows 1252" and "ISO-8859-1" and "UTF-8 without the byte order mark" -are completely identical! I had the false impression that when a file was saved in UTF-8, that there was an actual binary "marker" that specified this (e.g. binary marker = "This file is saved in UTF-8!") -there simply is no such thing. The only thing that would set "UTF-8" apart -binarilly speaking- is the BOM, and I had stripped that out, making the file exactly the same as plain old "ANSI" (since I didn't have any characters that required "UTF-8", like from other languages etc.). My text editor displays the current character encoding in the status bar, but since there was no way for it to tell whether it was saved with Windows 1252 or UTF-8, it just displayed that the file was encoded "windows default - ISO-8859-1". This is where I got confused. It turned out that my PHP script has been faithfully saving the file in UTF-8 the whole time, and everything was fine. I was just not educated enough about what actually changed when you save a file in UTF-8 but didn't have any characters that differed from ANSI (which in my case, the "change" was nothing, since ALL of the characters in my test document where interchangeable with ANSI). Well, this has been a learning experience! I hope that this post will help some poor ignoramus like myself, sometime in the future! :) And hopefully I am right about what I said above, and not flaunting my ignorance once again -lol Thanks again, to everyone who helped me! You guys really got me on the right track. Not the least of which was simply causing me to think about what I was asking more deeply. -Jon "Rasmus Lerdorf" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] > Jon M. wrote: >> No matter what I do to the strings to encode them in whatever format >> before using "fwrite", it ALWAYS seems to end up writing the actual file >> in "iso-8859-1". >> >> Isn't the encoding of the characters in PHP's strings, and the encoding >> of the actual binary file on your hard drive, two totally different >> things?
