Re: [ELPA] New package: pyim

[Zhu Zihao]

Hi, tumashu.

I'm a big fan of pyim input method, I would be very happy to see pyim
can be a part of GNU ELPA or even Emacs!

I just do some research on the issue we faced. We can extract the
bopomofo data from unihan database.

For example, the pinyin of CJK character "爱"(means love) is "ai". Can be found 
at
https://www.unicode.org/cgi-bin/GetUnihanData.pl?codepoint=7231.

The full database can be downloaded at
https://www.unicode.org/Public/UCD/latest/ucd/Unihan.zip. Unihan
database is licensed under Unicode license, a free license approved by
FSF(https://www.gnu.org/licenses/license-list.html#Unicode).

We can write a simple program to extract the pinyin of needed characters
in Unihan_Readings.txt. Unihan database contains almost all reading of
CJK character, we have to limit it to a subset. Maybe refer to
《通用汉字规范表》 (Table of General Standard Chinese Characters)
