Disallow Japanese Characters (no-japanese-character)

In an internationalized application, Japanese characters are not allowed. This rule helps to find out where Japanese characters are.

Rule Details

The following patterns are considered problems:

var str = "日本語";

The following patterns are not considered problems:

var str = "English";

// or

var str = this.getIntlMessage("i18n.key"); // using an i18n tool instead of regular Japanese characters

Rule Options

The rule takes an object option with the following keys:

{boolean} includeIdentifier

• In general, we don't check identifiers for l10n/i18n. If you would like to lint them, set includeIdentifier as true to enforce checking.

"i18n/no-japanese-character": [
  "warn",
  {
    "includeIdentifier": true
  }
]

{boolean} includeComment

• It's also not common to check comments for l10n/i18n, but you can set includeComment as true to enforce checking.

"i18n/no-japanese-character": [
  "warn",
  {
    "includeComment": true
  }
]

{array} excludeArgsForFunctions

• We exclude from the check the functions specified in the excludeArgsForFunctions option.

"i18n/no-japanese-character": [
  "warn",
  {
    "excludeArgsForFunctions": ["i18n", "l10n", "i18n.t"]
  }
]
