Android:发送短信 (sendTextMessage) 时出现 Unicode/Charset 问题

Question

基本上，我有一个可以在收到 SMS 后发送 SMS 的工作应用程序。

一切正常，除非 SMS 文本发送有“特殊字符”，即“é、à、í、ç”等。

我已经尝试了很多东西，包括字符集转换，但我就是无法让它工作...msgText 总是返回字符集编码问题。

这是发送消息的部分:

if (msgText.length() > 160) {
    ArrayList msgTexts = sm.divideMessage(msgText);
    sm.sendMultipartTextMessage(PhoneNumber, null, msgTexts, null, null);
} else {
    try {
        sm.sendTextMessage(PhoneNumber, null, msgText, null, null);
    } catch (IllegalArgumentException e) {
        e.printStackTrace();
    }
}

这是我在 msgText 上应用的字符集转换函数(但没有帮助):

public static String formatCharset(String txtInicial) {
    //-- Please notice this is just for reference, I tried every charset from/to conversion possibility. Even stupid ones and nothing helped.

    /*try {//-- Seems simpler, it should do the same as below, but didn't help
        msgText = new String(msgText.getBytes("UTF-8"), "ISO-8859-1");
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
    }*/

    Charset charsetOrigem = Charset.forName("UTF-8");
    CharsetEncoder encoderOrigem = charsetOrigem.newEncoder();
    Charset charsetDestino = Charset.forName("ISO-8859-1");
    CharsetDecoder decoderDestino = charsetDestino.newDecoder();

    String txtFinal = "";

    try {
        ByteBuffer bbuf = encoderOrigem.encode(CharBuffer.wrap( txtInicial ));
        CharBuffer cbuf = decoderDestino.decode(bbuf);
        txtFinal = cbuf.toString();
    } catch (CharacterCodingException e) {
        e.printStackTrace();
    }

    if (txtFinal.length() == 0) txtFinal = txtInicial;

    return txtFinal;
}

几近绝望，我什至在这里尝试了 unicode 消息传递的解决方案(也没有帮助):

无论如何，这里是(清理后 - 包是 com.THE.APPLICATION，主要 Activity 是 MAINACT)当它崩溃时的 LogCat(当尝试发送消息时，收到消息后):

发送有问题的消息文本示例:

VERBOSE/debug_tag(28218): msgText is: possível.

因此，它读取possível应该possível

请一些开明的灵魂帮助我。他/她将在我心中占有特殊的位置! :)

编辑:如果我心中的特殊位置不适合，我愿意花几 block 钱买一个可行的解决方案...

好的，这似乎已经通过简单地使用 sendMultipartTextMessage 而不是 sendTextMessage 来解决消息。

谁会想到...这是有道理的，因为 unicode 字符比“普通”字符使用更多的“空格”。
