L2/20-058 Title: Proposal to change the code chart font for 21 blocks in Unicode Version 14.0 Author: Ken Lunde Date: 2020-01-22 (replaces L2/19-386) This is a proposal to change the code chart font for 21 blocks—affecting 1,762 characters— that are CJK-related or otherwise include characters that are used primarily in CJK contexts and are therefore supported in fonts for typical CJK typefaces. The suggested target for this change is Unicode Version 14.0 (2021). The purpose of this font change is four-fold: • Reduce the number of fonts that are necessary for code chart production. • Improve the consistency of the glyphs for similar or related characters by using a uniform typeface design and typeface style, at least for characters whose glyphs do not need to ad- here to a particular specification.. • Simplify code chart font management by covering as many complete blocks as possible using a single font. • Ensure that the font is accessible via open source. The actual font, CJK Symbols, has been open-sourced in both TrueType and OpenType/CFF formats under the terms of the SIL Open Font License, Version 1.1, and is already available on GitHub. The font can therefore be updated to include glyphs for additional blocks, or to add glyphs for characters in blocks that are already supported. This is maintenance work that I plan to take on for the foreseeable future. Code Chart Excerpts The even-numbered pages of this proposal include the current—Unicode Version 13.0 BETA— code chart excerpts for the 21 affected blocks. These can be used to draw a comparison be- tween the current representative glyphs with those provided in the CJK Symbols font that are shown on the facing odd-numbered pages. Code Tables Starting from page 3, the odd-numbered pages include left-to-right, top-to-bottom code ta- bles that serve as a glyph synopsis for the CJK Symbols font. Some of these code tables include a special note at the end that points out a peculiarity or specifies an action that needs to be taken for code chart production. Of the 21 blocks that are covered, 19 are covered in their entirety as of the Unicode Version 13.0 repertoire. The two blocks that include glyphs for only a subset of their characters have an appropriate note inked in red. Block names are inked in blue, and serve as links to the perpetually-current code charts. 1 02B0 Spacing Modifier Letters 02FF Spacing Modifier Letters—only U+02EA & U+02EB 0 1 2 3 4 5 6 7 8 9 A B C D E F 02B 02C 02D 02E 02F U+02E ˪ ˫ 0 ʰ ˀ ː ˠ ˰ 02B0 02C0 02D0 02E0 02F0 1 ʱ ˁ ˑ ˡ ˱ 02B1 02C1 02D1 02E1 02F1 2 ʲ ˂ ˒ ˢ ˲ 02B2 02C2 02D2 02E2 02F2 3 ʳ ˃ ˓ ˣ ˳ 02B3 02C3 02D3 02E3 02F3 4 ʴ ˄ ˔ ˤ ˴ 02B4 02C4 02D4 02E4 02F4 5 ʵ ˅ ˕ ˥ ˵ 02B5 02C5 02D5 02E5 02F5 6 ʶ ˆ ˖ ˦ ˶ 02B6 02C6 02D6 02E6 02F6 7 ʷ ˗ ˧ ˷ 02B7 02C7 02D7 02E7 02F7 8 ʸ ˈ ˨ ˸ 02B8 02C8 02D8 02E8 02F8 9 ʹ ˉ ˩ ˹ 02B9 02C9 02D9 02E9 02F9 A ʺ ˊ ˪ ˺ 02BA 02CA 02DA 02EA 02FA B ʻ ˋ ˫ ˻ 02BB 02CB 02DB 02EB 02FB C ʼ ˌ ˜ ˬ ˼ 02BC 02CC 02DC 02EC 02FC D ʽ ˍ ˭ ˽ 02BD 02CD 02DD 02ED 02FD E ʾ ˎ ˞ ˮ ˾ 02BE 02CE 02DE 02EE 02FE F ʿ ˏ ˟ ˯ ˿ 02BF 02CF 02DF 02EF 02FF DRAFT The Unicode Standard 13.0, Copyright © 1991-2019 Unicode, Inc.
