推荐答案
Android的支持下面的编码
Android support the following encodings
- Xml.Encoding ISO_8859_1
- Xml.Encoding US_ASCII
- Xml.Encoding UTF_16
- Xml.Encoding UTF_8
US_ASCII不应该使任何问题。
US_ASCII shouldn't make any problems.
有关ISO_8859_1前人的精力，你检查 http://en.wikipedia.org/wiki/ISO/IEC_8859-1
控制字符0x00-0x1f到0x7f，0x9f和过滤。
当然，使用匹配的字体。
For ISO_8859_1 you sould check http://en.wikipedia.org/wiki/ISO/IEC_8859-1 for control chars 0x00-0x1f and 0x7f-0x9f and filter them. And of course use a matching font.
使用UTF_8或16个比较复杂，读Joels 绝对最低每一个软件开发人员绝对，积极必须知道关于统一code和字符集
Using UTF_8 or 16 is more complex, read Joels The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets
