Subject [jira] [Created] (LOG4NET-329) Allow creation of UTF-8 logs without a BOM.
Date Wed, 28 Mar 2012 02:29:22 GMT
Allow creation of UTF-8 logs without a BOM.
-------------------------------------------

                 Key: LOG4NET-329
                 URL: https://issues.apache.org/jira/browse/LOG4NET-329
             Project: Log4net
          Issue Type: Wish
          Components: Appenders
    Affects Versions: 1.2.11
         Environment: Windows 7.
            Reporter: Ben Monroe
            Priority: Minor


When an appender uses the "utf-8" encoding, output logs will append a BOM to the start of
a file. This is problematic when the log file is only supposed to output errors. Explorer
reports the file size as non-0, so the only way to know if an error actually occurred is to
open the log every time and check. This is not desirable.

Further, from the Unicode FAQ (http://unicode.org/faq/utf_bom.html), a BOM is unnecessary
for UTF-8 since it is already a sequence of bytes, so there are no endian problems to solve
in the first place.

Removal of the BOM is not necessary, but should also provide a means to use UTF-8 without
a BOM. That could be a new encoding name such as "utf-8_nobom" or as a separate attribute
such as "bom=false" or something else.
