UTF-8 – 永夜 https://www.shuijingwanwq.com 没有不值得去解决的问题，也没有不值得去学习的技术！ Wed, 03 Jun 2026 13:31:18 +0000 zh-Hans hourly 1 https://wordpress.org/?v=7.0 Ubuntu 打开 Windows 文档提示“无效字符”？我的解决方法 https://www.shuijingwanwq.com/2026/06/03/15636/ https://www.shuijingwanwq.com/2026/06/03/15636/#respond Wed, 03 Jun 2026 13:31:16 +0000 https://www.shuijingwanwq.com/?p=15636 浏览量： 39

从 Windows 换到 Ubuntu 后，打开以前写的文档时弹出了“检测到无效字符”的提示，内容显示为乱码。这里记录一下我亲测有效的解决方法，全程只需鼠标操作。

一、问题现象

在 Ubuntu 26.04 系统中，使用系统自带的文本编辑器（GNOME 默认编辑器）打开一个之前在 Windows 10 下编写的 .txt 文档时，弹出一个错误提示：

检测到无效字符
发生了编码转换错误因此使用了回退字符。

检测到无效字符 发生了编码转换错误因此使用了回退字符。

文档内容显示为一堆类似 D6C0E0CFC2B5C4... 的乱码，无法阅读。

二、原因简析

这个问题通常是因为 Windows 和 Linux 默认使用的文字编码不同。

  • Windows 10（简体中文版）默认使用 GBK（或 GB18030）编码保存文本文件。
  • Ubuntu 默认使用 UTF-8 编码。

Ubuntu 的文本编辑器自动检测编码时，误把 GBK 文件当成 UTF-8 去打开，遇到无法识别的字节就报了“无效字符”的错误。

三、解决步骤（全程鼠标操作）

以下是我实际操作的过程。

第 1 步：手动将编码改为 GBK

  1. 弹出“检测到无效字符”对话框时，点击其中的 「更改编码(E)…」 按钮。
  2. 在弹出的“更改编码”窗口中，默认选中的是 UTF-8。
    从列表中找到并选择 简体中文 (GBK)（也可以选择 GB18030 或 GB2312）。

我选择的是 GBK。

此时编辑器会使用 GBK 编码重新加载文档，内容恢复正常，中英文均可正确显示。

此时编辑器会使用 GBK 编码重新加载文档，内容恢复正常，中英文均可正确显示。

第 2 步：将文档另存为 UTF-8（覆盖原文件）

虽然文档已经可以正常阅读，但它本质上还是 GBK 编码。为了以后在任何 Linux 环境下都能直接打开，可以把它转换成 Ubuntu 通用的 UTF-8 编码。

操作如下：

  1. 点击编辑器菜单栏 另存为。
  2. 在保存对话框中找到 显示选项 – 编码 ，将其从“自动检测”改为 UTF-8。
  3. 保持文件名和路径不变（覆盖原文件），点击 替换。
  4. 关闭文档，再重新打开。
在保存对话框中找到 显示选项 - 编码 ，将其从“自动检测”改为 UTF-8。

重新打开后不再出现错误提示，内容完美显示。这个文件以后在大多数现代编辑器中（包括 Windows 下的新版本记事本）也可以正常打开。

四、如何避免以后再次遇到类似问题

如果经常需要在 Ubuntu 中打开从 Windows 拷贝过来的文本文件，可以尝试以下的习惯。

在 Windows 下创建文件时直接保存为 UTF-8（我大部分文件皆是 UTF-8）

  • 使用 Windows 自带的 记事本：编辑完成后点击“文件”→“另存为”，在“编码”下拉框中选择 UTF-8。
  • 使用 Notepad++：打开文件后点击菜单“编码”→“转为 UTF-8 无 BOM 编码”。这样保存的文件在 Ubuntu 下兼容性更好。

五、总结

遇到“无效字符”错误时，只需两步即可解决：

  1. 更改编码为 GBK → 让文档正常显示。
  2. 另存为 UTF-8 → 永久解决编码问题。

整个过程不需要使用命令行，在图形界面中点几下鼠标就可以完成。希望这次记录能对遇到类似情况的朋友有所帮助。

$optionText = '多选一，多选二';
$optionInputs = preg_split('/[\r\n,，；;、]+/', $optionText);
2、在使用 preg_split() 之前，先将字符串转换为 UTF-8。u 表示 Unicode（UTF-8）模式，避免中文字符拆分错误。 


$optionText = mb_convert_encoding('多选一，多选二', 'UTF-8', 'auto');
$optionInputs = preg_split('/[\r\n,，；;、]+/u', $optionText);
3、拆分正确，不再报错。

14、Heroku 平台支持多种语言，在进行应用部署时，Heroku 会自动检查应用的代码是用什么语言写的，然后再接着执行一系列针对该语言的操作来准备好程序运行环境。Laravel 应用默认会包含 package.json 文件，但当 Heroku 检查到该文件时，它会认为此应用是用 Node.js 写的，因此我们需要对应用的 buildpack 进行声明，告诉 Heroku 说我们的应用是用 PHP 写的。如图12

27、在 Heroku 上使用 PostgreSQL 来作为我们应用的数据库。安装 PostgreSQL 扩展。Heroku 将为我们生成一个唯一的数据库 URL – DATABASE_URL，我们可以通过命令：heroku config 查看 Heroku 的所有配置信息。如图24

28、在本地开发中，我们使用了 MySQL 来作为数据库储存，但在 Heroku 环境上我们要改为使用 PostgreSQL 来作为数据库储存。因此在进行数据库设置时，我们需要对当前环境进行判断。如果环境为本地环境，则使用 MySQL 数据库，若为 Heroku 环境，则使用 PostgreSQL 数据库。我们可以通过为 Heroku 新增一个 IS_IN_HEROKU 配置项来判断应用是否运行在 Heroku 上。一般来说，应用的数据库都在 config/database.php 中进行配置，因此我们需要针对该配置文件，来为不同环境的数据库连接方式定义一个帮助方法，以便根据应用不同的运行环境来指定数据库配置信息，我们需要新建一个 helpers.php 文件并写入以下内容： 
<pre class="wp-block-syntaxhighlighter-code">

<?php

function get_db_config()
{
    if (getenv('IS_IN_HEROKU')) {
        $url = parse_url(getenv("DATABASE_URL"));

        return $db_config = [
            'connection' => 'pgsql',
            'host' => $url["host"],
            'database'  => substr($url["path"], 1),
            'username'  => $url["user"],
            'password'  => $url["pass"],
        ];
    } else {
        return $db_config = [
            'connection' => env('DB_CONNECTION', 'mysql'),
            'host' => env('DB_HOST', 'localhost'),
            'database'  => env('DB_DATABASE', 'forge'),
            'username'  => env('DB_USERNAME', 'forge'),
            'password'  => env('DB_PASSWORD', ''),
        ];
    }
}

</pre>
29、新增 helpers.php 文件之后，还需要在项目根目录下 composer.json 文件中的 autoload 选项里 files 字段加入该文件。如图25

        },
        "files": [
            "app/helpers.php"
        ]
    },
30、修改保存后运行以下命令进行重新加载文件即可，如果有可能影响到本地环境的程序运行，建议在 Sail 环境中执行相应命令。如图26

return [

    'default' => $db_config['connection'],

1、在 Yii 2.0 中报错：Malformed UTF-8 characters, possibly incorrectly encoded.

2、查看代码如下

<?php

use Yii;
use yii\web\HttpException;
use yii\base\Exception;
use yii\data\ActiveDataProvider;
use yii\data\DataFilter;
 
class IndexAction extends \yii\rest\IndexAction
{
    /**
     * @return int|string|ActiveDataProvider|DataFilter|null
     */
    public function run()
    {
        try {
            Yii::$app->db->open();
            if (!Yii::$app->redis->ping()){
                throw new HttpException(500, 'Redis is unavailable.');
            } elseif (!Yii::$app->db->getIsActive()){
                throw new HttpException(500, 'Database is unavailable.');
            } else {
                return 200;
            }
        } catch (Exception $e) {
            $res = Yii::$app->response;
            $res->statusCode = 500;
            return $e->getMessage();
        }
    }
}

3、打印输出 $e->getMessage()，其中包含乱码。如图1

4、编辑代码，mb_convert_encoding — 转换字符的编码。响应状态码为：500，响应体为：”SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: 不知道这样的主机。 “。如图2

{
    /**

     */
    public function run()
    {
        try {
            Yii::$app->db->open();
            if (!Yii::$app->redis->ping()){
                throw new HttpException(500, 'Redis is unavailable.');
            } elseif (!Yii::$app->db->getIsActive()){
                throw new HttpException(500, 'Database is unavailable.');
            } else {
                return 200;
            }
        } catch (Exception $e) {
            Yii::$app->response->statusCode = 500;
            $message = mb_convert_encoding($e->getMessage(), "UTF-8", ["UTF-8", "GBK", "GB2312", "BIG5"]);
            return $message;
        }
    }
}

5、初步推测，不知道这样的主机是由 Windows 10 系统返回的。与是否是中文无甚关系，而是与中文本身的编码存在关系。因为 message 为：”Failed to open redis DB connection (tcp://localhost:63799, database=57): 10061 – 由于目标计算机积极拒绝，无法连接。\r\n” 时，未转换字符的编码也是可以正常运行的。
