Comment 8 for bug 48326

The following is the code from firefox-runner in drapper's firefox deb diff.

+if [ "x${MOZ_DISABLE_PANGO}" = x ]; then
+ if egrep '^(bn|gu|hi|kn|ml|mr|ne|pa|ta|te)_' \
+ /var/lib/locales/supported.d/*[^~] >/dev/null 2>&1; then
+ MOZ_DISABLE_PANGO=0
+ else
+ MOZ_DISABLE_PANGO=1
+ fi
+ export MOZ_DISABLE_PANGO
+fi
+if [ "x${MOZ_DISABLE_PANGO}" = x0 ]; then
+ unset MOZ_DISABLE_PANGO
+fi

Can you please try installing the Telugu language support and also setting MOZ_DISABLE_PANGO=0 instead of MOZ_ENABLE_PANGO=1.

We have tested Flight 5 for Drapper Drake and after Telugu langauge support is installed, firefox rendering was fine.
