It actually works but only if the content is encoded as UTF-8/16/32 - ie. StreamReader() specifically has an overload that's supposed to help with detection of byte order marks and based on that is supposed to sniff the document's encoding.

It turns out part of the problem is the code I snatched from Douglas Crockford's original C# minifier code, but there's also an issue with some of the code I added to provide string translations. I posted a JavaScript Minifier application yesterday and somebody correctly pointed out that the text encoding was incorrect. StreamReader supports byte order mark detection and in most cases that seems to be working Ok, but if you deal with a variety of different file encodings for input files using the default detection comes up short. This means that the detection of the encoding based on the content is based just on heuristic, so doesn't guarantee that the encoding used to open the file is correct.I keep running into issues in regards to auto-detection of file types when using StreamReader. You can use the exec function of PHP to run the iconv program with the mentioned arguments, available on every UNIX based OS or in Windows ( using Cygwin).Īs mentioned, most of the text editors that use the automatic encoding detector decide which encoding to use according to the content, so normally although the strings stored in the file with PHP that have the Windows-1252 encoding (CP1252), the UTF-8 mode will be used. In PHP, you can achieve such thing using the iconv function, trying to detect the encoding of your data (usually UTF-8) and convert it into the new format namely Windows-1252 (CP1252): "encoded_output_file.txt" Unicode also has control characters in that range. Windows-1252 (the code page most commonly referred to as "ANSI") is similar to ISO 8859-1 (Latin-1), except that Windows-1252 has printable characters in the range 0x80.0x9F, where ISO 8859-1 has control characters in that range.

They were based on drafts submitted for ANSI standardization, but ANSI itself never standardized them. In some enterprises, this process is necessary as the software of other big companies is out of date and doesn't operate well with the UTF-8 default encoding, so you will need to change obligatorily the encoding of your generated files to the named "ANSI" codification. The term "ANSI" when applied to Microsoft's 8-bit code pages is a misnomer. This leads to a simply conjecture, the charset of the text file is defined by its data, so you need to convert the data that you will write into the file to a specific format. The fwrite function of PHP or file_put_content doesn't care about metadata of the file, it just writes the given data to the storage and that's it.
