### [9.1. First Line Indentation: the ‘text-indent’ property](https://www.w3.org/TR/css-text-4/#text-indent-property)

In Japanese text, the style of indenting the first character of a paragraph is typically achieved by inserting a full-width space. To achieve this indentation using the 'text-indent' property without inserting characters, it is necessary to define a unit that accounts for the width of the full-width space character of the font. Although the ic unit, which represents the width of Kanji, is currently defined, it is not uncommon for the widths of Kanji and full-width space characters to differ in fonts. One example is the default MS P Gothic on Windows, and another is AXIS Condensed / Compressed. In the latter, Kanji and Kana are monospaced, yet Kana is set narrower than Kanji, and both full-width spaces and punctuation have the same width as Kana.

Below is feedback from the Type Project:
> "In AXIS Font Condensed, as you mentioned, full-width spaces and punctuation are based on the Kana width. Therefore, it is understood that a typesetting system based on Kana is being used. In other words, a text composed solely of Kana and punctuation would serve as the typesetting standard for AXIS Font Condensed.
> Just as proportional Western text intervenes as an exceptional element in the normal setting of square-bodied Kana and Kanji, in AXIS Font Condensed, it is simpler to think of the typesetting system as being based on Kana width, involving Kanji and proportional Western text.
> In fact, when writing texts like this, it feels natural to intermittently insert Kanji into a flow primarily composed of Kana.
> Based on this, the appropriate amount of first-line indentation in AXIS Font Condensed would be the width of a full-width space (760/1000)."

As a result of the discussion, it was concluded that a definition of a unit representing the width of a full-width space character is needed.

#### Actions
Mr. Kida will create an issue on [csswg-drafts](https://github.com/w3c/csswg-drafts/labels/css-text-4).
