Chinese T9

Chinese T9 supports both Phrasal Pinyin and Stroke input methods.

Phrasal Pinyin or BoPoMoFo allows users to input a phrase by continuously entering Pinyin or BoPoMoFo for the phrases without selecting each character first. For example: for the phrase "北京", users can enter the key sequence for "Beijing" or "ㄅㄟㄐーㄥ" and then select "北京" from the selection list. This feature also supports the Jianpin (拼) feature that allows users to retrieve a phrase by entering the first pinyin letter of the first few characters. For example, the user would only need to type 'b' or 'bj' or 'bjd' or 'bjdx' to retrieve 北京大学.

Stroke Input
Stroke Input allows users to input a phrase by entering the full or first few strokes for each character in the phrase separated by a delimiter. For example: to enter the phrase "北京大学" (Beijing University), if "└┘" represents a delimiter, users can enter the full or partial stroke sequence 丨 or 丨└┘丶 or 丨└┘丶└┘一 or 丨└┘丶└┘一└┘丶 to retrieve "北京大学" from the selection list.

Mohu Pinyin
Mohu Pinyin provides support for regional variations in pronunciation or spelling by interchanging Mohu pinyin pairs. For example: enter "ZongGuo" to retrieve the phrase "中国" which has "ZhongGuo" as the correct Pinyin.

User Database (UDB) Phrasal
This feature allows users to add personal or commonly selected phrases which are not available in the phone database, such as names, personal addresses, etc. Users just need to add a phrase once and it will be added to their personal dictionary. Additionally, PTI will position this newly added phrase earlier in the selection list.

Modeless Input
This feature allows users to enter a message that includes both Chinese and English characters, numbers and symbols without switching modes. Say, for example, a user wants to enter the message "你好, 我是Mary 请回电123456789J", which is a combination of phrasal Pinyin, symbols (including emoticons), numbers and English characters. If the original input mode is Pinyin, the message can be completed in Pinyin mode with the following numeric key input: 64-1-97-6279-743-123456789-111.

Chinese Name Reordering
This feature reorders Chinese names so that they appear first in the selection list. This is useful when entering contacts in a contact management application.

T9 also allow users to input numbers, symbols, emoticons and English characters while in Chinese input mode without having to switch modes.
