Answer 1

这里我从网站找了一个拼音转汉字的字库，然后修改了一些代码，测试了你问题里的"滘、呃"等字都能成功转换，你可以看一下，测试代码我就不贴了，由于字库较大，超过了20000字，所以你看以下字库地址：
http://www.missde.cn/zuopin/cn2pinyin.html

Answer 2

不知道你的字库有多大，字库越大，兼容性越强，可看下php汉字转拼音函数和类，共20901字，131K，对于哪些用得非常少的生避字可以在字典里面加进去。

Answer 3

这里也有一个，是把字典给搬上来了，应该能满足你的要求，你可以看一下，支持原版：

Answer 4

汉字转拼音，java下请用请用pinyin4j，太省事了，哈哈

Answer 5

这是网上一个解决你问题方案包，已经有人打包了，你看看：
