Highlight Bad Chars

Extension to highlight bad characters such as No-break space ( ) and the Greek question mark (;) in your source files.

With this package you'll easily notice invisible and easy-to-confuse characters, which can be the cause for incredibly annoying syntax errors in source code.

Save yourself the burden of debugging invisible bugs for hours!

Settings

Additional unicode characters can be specified in Visual Studio Code 'Settings'. 'highlight-bad-chars.additionalUnicodeChars' is the setting name array object that is used. To add additional unicode characters, add a new string array value with the unicode character to mark as shown in example below.

    "highlight-bad-chars.additionalUnicodeChars": [
        "\u200E",
        "\u200F"
    ],

The default "bad char" decoration style can be configured through the highlight-bad-chars.badCharDecorationStyle and defaults to:

    "highlight-bad-chars.badCharDecorationStyle": {
        "cursor": "crosshair",
        "backgroundColor": "rgba(255,0,0,0.3)",
        "borderWidth": "1px",
        "borderStyle": "solid",
        "borderColor": "rgba(255,0,0,0.6)"
    }
