[Rpm-maint] Inconsistency between RPMTAG_Summary and %{SUMMARY}

[learny]

Hello All:

First-off, thanks for the responses.  It was all very helpful.

As suggested by Pixel, I first checked the XML of the header.  It matched
that of the API call (i.e. also different from the command-line output).

Next, I took Peter's advice and changed the default language setting.  The
install had this as en_US.utf-8.  Changing this to 'en' made the output the
same (i.e. export LANG=en).

Thanks again for the help in resolving this issue!
Christopher

I suspect you are running into a translated string.  If you set your
environment to not specify a language, do you still see the issue?

While most programs are assumed to be have US English text as the
default, it is possible to have a US English transation associated with
the string.  I suspect in this case "CPU frequency adjusting daemon. "
is in the RPM header as the "C" (untranslated) string and "CPU frequency
adjusting daemon" is in the header or look-aside list as the string that
matches your language.

Thanks.
Peter
