Shortcut method for testing new locale file with glibc in Fedora

I had some discussion on Indlinux list about testing newly locale file/collation with glibc but that time i didn't no the short cut method, i was building glibc with changes and then testing it, it was taking long time. :(
Had a discussion with Ulrich Drepper on this and he suggested good tips on testing locale/collation in 10 minutes, so sharing with all :)

step 1:
- make a new folder

step 2:
- copy the locale file there
ex: cp mr_IN to NEW_FOLDER/mr (note i have changed name of locale file)

step 3:
- edit mr (do changes you want example you can add collation info etc)

step 4:
- run following command
$localedef -i ./mr -f UTF-8 ./mr_IN
that's it.
It will create new folder mr_IN with all locale information

step 5:
- for testing with these new changes locally, use following command
*make sure you are in new folder created in first step
LOCPATH=$PWD LC_ALL=mr_IN date

step 6:
for adding this into archive permanently use following command
need to be root
root$ localedef --add-to-archive mr_IN

Proposal for additional Deprecated Characters from Unicode

0953 ( ॓ ) DEVANAGARI GRAVE ACCENT
0954 ( ॔ ) DEVANAGARI ACUTE ACCENT

I saw this earlier but just remembered when i saw pango renders U+0953 and U+0954 characters as independent vowel even though they are dependant(dont know what is exact problem).

Unicode Public Review issue 122 dated 2008-08-04, has proposed these two characters as deprecated.
http://www.unicode.org/review/pr-122.html

As a devanagari script user i have never used these in my writing, but i think these two characters are added specifically for vedic.
