如何在表格中满足td的输入字段中编写bengali？

Question

在输入字段内写入bengali是否正常工作？但是没有在表的contenteditable td内工作。所以我的问题是如何在表的contenteditable td内写入bengali？

var matched, browser;

jQuery.uaMatch = function(ua) {
  ua = ua.toLowerCase();

  var match = /(chrome)[ \/]([\w.]+)/.exec(ua) ||
    /(webkit)[ \/]([\w.]+)/.exec(ua) ||
    /(opera)(?:.*version|)[ \/]([\w.]+)/.exec(ua) ||
    /(msie) ([\w.]+)/.exec(ua) ||
    ua.indexOf("compatible") < 0 && /(mozilla)(?:.*? rv:([\w.]+)|)/.exec(ua) || [];

  return {
    browser: match[1] || "",
    version: match[2] || "0"
  };
};

matched = jQuery.uaMatch(navigator.userAgent);
browser = {};

if (matched.browser) {
  browser[matched.browser] = true;
  browser.version = matched.version;
}

// Chrome is Webkit, but Webkit is also Safari.
if (browser.chrome) {
  browser.webkit = true;
} else if (browser.webkit) {
  browser.safari = true;
}

jQuery.browser = browser;
