Status: NEW

(Core :: Internationalization, task, P3)

Description

[Zibi Braniecki [:zbraniecki][:gandalf]]

Spin off from bug 1612379.

It seems that our data filters for ICU bundle more data than Chromium's - https://chromium.googlesource.com/chromium/deps/icu/+/refs/heads/master/filters

Let's see why.

With collationUCAData=implicithan:

• Size (icudt65l.dat): 7,751,056 -> 7,410,288

When additionally removing some Chinese collation data:

• Size (icudt65l.dat): 7,410,288 -> 7,194,944

When additionally removing some currencies:

• Size (icudt65l.dat): 7,194,944 -> 6,534,064

The currencies would be an observable regression for SM Intl if I'm not mistaken, but what about the previous two?
