Bootstrap List过滤土耳其语“İ”字符的问题

Question

我使用引导程序列表过滤器（see github）但是我遇到了土耳其语“İ”字符的问题，当我输入小写“i”时我没有结果。

您可以看到我的代码段：

public void updateColors() {
    EditorUI editorUI = Utilities.getEditorUI(textComponent);
    if (editorUI == null) {
        return;
    }
    String mimeType = NbEditorUtilities.getMimeType(textComponent);
    FontColorSettings fontColorSettings = MimeLookup.getLookup(MimePath.get(mimeType)).lookup(FontColorSettings.class);
    Coloring lineColoring = Coloring.fromAttributeSet(fontColorSettings.getFontColors(FontColorNames.LINE_NUMBER_COLORING));
    Coloring defaultColoring = Coloring.fromAttributeSet(fontColorSettings.getFontColors(FontColorNames.DEFAULT_COLORING));

    if (lineColoring == null) {
        return;
    }

    // use the same color as GlyphGutter
    final Color backColor = lineColoring.getBackColor();
    // set to white by o.n.swing.plaf/src/org/netbeans/swing/plaf/aqua/AquaLFCustoms
    if (org.openide.util.Utilities.isMac()) {
        backgroundColor = backColor;
    } else {
        backgroundColor = UIManager.getColor("NbEditorGlyphGutter.background"); //NOI18N
    }
    if (null == backgroundColor) {
        if (backColor != null) {
            backgroundColor = backColor;
        } else {
            backgroundColor = defaultColoring.getBackColor();
        }
    }
}

$(window).load(function(){
$('#mylist').btsListFilter('#filterinput', {
    itemChild: 'span'
});
});

使用小写输入 istanbul 。
