Contacts

Feature description

Search contacts saved as Chinese by Pinyin.

Just like HenriDellal/emerald-dialer@ee9af2b

Why do you want this feature?

T9 is much much much faster than we input Chinese.
Each Chinese Android ROM's dialer supports T9 search for contacts.
Each, without exception
Just for example, 中文, T9 use 2 key, 99 (get zw).
Input Chinese we need 9 key, zhongwen + space.
BTW, name is very very very hard to input for Chinese. Some characters are very rare and have a lot of duplicate codes when input.
Sometime input Chinese name to search slower than scroll the contact list.
