CJK Font Variants

  • The CJK Font Variants utility displays simultaneously any string of CJK (Chinese/Japanese/Korean) characters in five different typefaces belonging to the open-source set of Google Noto CJK Fonts:
Language Code Typeface
Japanese JP Noto Sans CJK JP Regular
Korean KR Noto Sans CJK KR Regular
Simplified Chinese SC Noto Sans CJK SC Regular
Traditional Chinese TC Noto Sans CJK TC Regular
Hong Kong Chinese HK Noto Sans CJK HK Regular
  • Additionally, it is possible to specify a set of logographic glyph variants for display by using the East Asian Variant drop-down menu.
  • CJK characters can be entered either directly in the "Characters" input field, or using a series of code points in hexadecimal format in the "Code Points" input field.
  • It is also possible to input predefined strings of CJK characters selected from the Samples ▾ pop-up menu; some of them make use of the information found in the StandardizedVariants.txt or IVD_Sequences.txt data files.
  • As a convenience, the input fields can be emptied using the Clear button.
  • In output, the standard Unicode code point format U+7ADC is used, i.e. "U+" directly followed by 4 or 5 hex digits.
  • In input, more hexadecimal formats are allowed, including Unicode escape sequences, such as \u9F8D or \u{20B9F}. Moving out of the field or typing the Enter key converts all valid codes to standard Unicode code point format.

JavaScript Runner

  • The JavaScript Runner utility lets you execute JavaScript code, and comes with several sample scripts related to Unicode, Unihan and emoji; it is useful for quick testing/prototyping or data processing.

Regex Properties

  • The Regex Properties utility displays all the Unicode 12.0 properties available for regular expressions, used in particular in this app by the Emoji Data Finder, Unicode Data Finder and Unihan Data Finder utilities.

  • These properties are suitable to build Unicode-aware regular expressions in JavaScript (ECMAScript 6) using the 'u' flag.

  • Unicode properties fall into four groups, which can be displayed individually using the Category drop-down menu:

    • General Category properties
    • Binary properties
    • Script properties
    • Script Extensions properties
  • For General Category properties, prefixing with General_Category= (Canonical) or gc= (Alias) is optional. Use the Optional Prefix checkbox to control whether the prefix is included or not.

  • Groupings:

    Property Description
    Cased_Letter Uppercase_Letter | Lowercase_Letter | Titlecase_Letter
    Letter Uppercase_Letter | Lowercase_Letter | Titlecase_Letter | Modifier_Letter | Other_Letter
    Mark Nonspacing_Mark | Spacing_Mark | Enclosing_Mark
    Number Decimal_Number | Letter_Number | Other_Number
    Punctuation Connector_Punctuation | Dash_Punctuation | Open_Punctuation | Close_Punctuation | Initial_Punctuation | Final_Punctuation | Other_Punctuation
    Symbol Math_Symbol | Currency_Symbol | Modifier_Symbol | Other_Symbol
    Separator Space_Separator | Line_Separator | Paragraph_Separator
    Other Control | Format | Surrogate | Private_Use | Unassigned
  • \P{…} is the negated form of \p{…}. Use the Negated checkbox to toggle between the two forms.

  • Notes:

    • \p{Any} is equivalent to [\u{0}-\u{10FFFF}]
    • \p{ASCII} is equivalent to [\u{0}-\u{7F}]
    • \p{Assigned} is equivalent to \P{Unassigned}

Building

You'll need Node.js installed on your computer in order to build this app.

git clone https://github.com/tonton-pixel/unicopedia-plus
cd unicopedia-plus
npm install
npm start

If you don't wish to clone, you can download the source code.

Several scripts are also defined in the package.json file to build OS-specific bundles of the app, using the simple yet powerful Electron Packager Node module.
For instance, running the following command will create a Unicopedia Plus.app version for Mac OS X:

npm run build-darwin
