Overview

Plangothic Project (Chinese: 遍黑体项目) is based on Source Han Sans CN and takes the Chinese Mainland variant ideographs as the standard to supplement the CJK Unified Ideographs Extension blocks. Initiated around June 2020.

Coverage

We have completed all CJK extension blocks other than Extension B. Also, Extension C, D, E, F and Extension I require further refinement. Other non-CJK ideographs are partly available.

Warning

This font is currently uncompleted and still lacks large numbers of CJK ideographs.

Contributors

There are also many other people who have supported and participated in the project. We would like to thank them.

FAQ

Q1: Why are there two font files for Plangothic?

A1: Because the maximum number of glyphs a font can hold is limited (to 65535), while the total count of CJK ideographs is much greater than this value.

Q2: What is the difference between fallback and allideo versions for P1?

A2: The fallback version is suitable for users who currently have installed fonts that CAN DISPLAY all CJK ideographs, and the CJK ideographs we have not included will be empty. The allideo version is suitable for users who currently have installed fonts that CANNOT DISPLAY all CJK ideographs, in which the CJK ideographs that have NOT been included will be replaced by the Hanazono Mincho font. Both files can be used to find out our current progress. When this project has completely covered all CJK ideographs, the fallback file will be removed.

Q3: Why P1 is divided into two types?

A3: Because all characters in extensions G and H covered by P2, have been included, so there is no need to divide P2.

Q4: Why does this project just include a small amount of CJK ideographs in the URO and extensions A?

A4: Since the purpose of this project is "supplement all the extension blocks of CJK Unified Ideographs based on Source Han Sans CN", needs of using CJK ideographs in the URO and Extension A blocks can be solved by directly using the Source Han Sans font. As for these CJK ideographs scattered in the URO and Extension A, included in this project are CJK ideographs with glyph changes in Unicode or inconsistent with the purpose of this project. Before adding these CJK ideographs to the project, they have been compared with other mainstream fonts and glyphs in the Unicode.

Q5: Will there be a version containing other weights (or other local glyphs) in the future?

A5: Since the quantities of this project are too large, so this request is not in our reach by now. If you have such ideas, you can make a derivative font version of the project with your requirements.

Q6: Why is there no Complex Text Layout (CTL) and/or Ideographs Variation Selectors (IVSs) in this font?

A6: The fonts of this project orientate themselves as pragmatic tool fonts, that is they are not responsible for precise typesetting but only for display (see Unifont and Noto Unicode developed by My1l). Using CTL to typeset and display these scripts, and displaying regional variation ideographs other than the CN variant using IVSs is OUTSIDE the coverage of the project. If you have such ideas, you can produce derivation fonts of this project by yourself if in need.

Q7: Can the TTC font from this project (i.e., a collection of multiple TrueType fonts) be directly used on smartphones or within software? Can it be installed on a phone to display all font styles simultaneously? Are there compatibility issues across software platforms or is it limited to specific platforms?

A7: The TTC font from this project is compatible with Windows platforms and works seamlessly there. However, on mobile devices, directly installing a TTC font file typically results in displaying only one font style (usually P1) due to technical constraints. To display all font styles within software applications, special configurations may be required. Compatibility with TTC fonts can vary across different platforms, often requiring additional steps. Detailed instructions for installing Plangothic on an Android phone are provided here.

Detailed instructions for installing Plangothic on a mobile phone

To install the Plangothic TTC font on an Android phone, follow these steps:

  1. Backup the /system/etc/fonts.xml and /system/etc/font_fallback.xml files of your current phone system (if available).
  2. Open the system/etc/fonts.xml and /system/etc/font_fallback.xml files.
  3. After the closing </family> tag of <family lang="ko">, insert a new line.
  4. Add the following XML code snippet with correct indentation:
    <family>
        <font weight="400" style="normal" index="0">Plangothic.ttc</font>
        <font weight="400" style="normal" index="1">Plangothic.ttc</font>
    </family>

After completing these steps, restart your phone to apply the changes. If you encounter issues, verify that the font files have been correctly updated and ensure that your device permissions allow modifications to system files.

We also welcome technical personnels in font production and accept you to continue to improve this project. You can contact the author through said information. The development of this project is inseparable from your publicity and encouragement.

  3. The members of this project are not professional font designers, so the font structure may not be aesthetically pleasing, and the added text may have a slight inconsistency compared to the original version. In addition, due to the limited time and energy of the members, there is no extra time for the project to refine. Some parts of the Chinese characters will be assembled very rigidly. Therefore, we cannot guarantee the accuracy of the font data and whether the expected presentation effect can be perfectly reproduced on your device. The author makes no express or implied warranties about this font, nor assumes any responsibility for any claims, damages, or attributable reasons arising from your use of this font.

  4. Some of the Chinese Mainland variant ideographs included in this font DO NOT fully follow the fonts displayed in the Unicode charts file. If you mind or cannot accept, please do not use this font.

  5. This project borrows and/or refers to other tools and/or open-source font projects in part or whole, mainly including:

  6. The glyphs data of this project is provided online by Hulenkius through SVG files. Users can obtain them through the link "https://seeki.vistudium.top/SVG/{lowercase_glyphs_hexadecimal_code}.svg".

    For example, the display result of <img src="https://seeki.vistudium.top/SVG/2ebf0.svg"/> will be:

Important

  • The online SVG files only include CJK Unified Ideographs Extension blocks B to Extension I.
  • The online SVG files may not simultaneously synchronize with the updates of this project, please use with discreation.

    • Status: Not created.

Warning

  1. Strictly speaking, Planicon Project and Planfixibit Project does not meet the requirements for "The Planiverse", but still included for convenience.
  2. Prone to Planicon Project, Plankangxi Project, and Planfixibit Project copyright disputes, its reservation needs to be discussed.
