The characters in text files can be encoded in various ways. Common are the character encodings:
That can be done also on using Save as with the Encoding option and the line ending option on button Save in the Save as dialog window.
The character encoding and the line ending type of the active file is shown by UltraEdit and UEStudio in the status bar at the bottom of the main application window.
The script below makes it simple to convert UTF-8 and UTF-16 encoded files to ANSI with using the code page as defined by the configuration setting Default code page (for ANSI encoding) and Unix or Mac line endings to DOS/Windows line endings.
The output window shows information about the file on which this script was run as well as the applied conversion if any conversion was run at all.
The character encoding declaration of an XML file is also adapted by the script. Please configure the string value of the variable sXmlEncoding in the script according to the default code page for ANSI encoded files.
The character set declaration of an HTML / XHTML file is also adapted by the script. Please configure the string value of the variable sHtmlEncoding in the script according to the default code page for ANSI encoded files.
- ANSI which is a synonym for one byte per character encoded text using a code page.
- UTF-8 without or with a byte order mark.
- UTF-16 Little Endian without or with a byte order mark.
- UTF-16 Big Endian without or with a byte order mark.
- DOS/Windows with carriage return + line-feed.
- Unix/Linux with just line-feed.
- Mac (prior Mac OS X) with just carriage return.
