  1. Glyph substitution not working in v28.7.1

    In v28.7.1, if the formatting of the character immediately before a glyph substitution is different, the glyph substitution does not work, and the default glyph is displayed instead. This bug occurs just by opening an ai file from a previous version. It's an extremely serious bug.


    v28.7.1でグリフ置換が機能しない

    v28.7.1では、グリフ置換の直前の文字の書式が異なると、グリフ置換が機能せず、デフォルトのグリフが表示されてしまいます。このバグは、以前のバージョンのaiファイルを開いただけで発生します。非常に深刻なバグです。

  2. Installed Fonts not showing

    Previously installed fonts not showing anymore. Says the fonts are missing but it worked previously and maybe 1 in 10 times it will have no error and the fonts will show. These fonts exist on my PC so it's not a cloud issue as far as i can see.

  4. Upon reopening Ai files, it shows that fonts are missing when they aren't

    To fix the "error" I have to navigate to Adobe fonts, uninstall each font one by one, as uninstalling a font family all at once doesn't fix the issue, then individually reinstall each font. Super tedious and taxing to workflow. Issue is across multiple files, all that I have created on the same device that presents the "missing font" dialogue so I know it isn't a file issue. Please fix.

  5. Morisawa Fontsの和文バリアブルフォントDriveFluxが使えない

    いつのバージョンからかMorisawa Fontsの和文バリアブルフォントDriveFluxが急に使えなくなりました。macOS 15.6、Illustrator 2024 29.7.1を使用しています。2024の最初の方は使えてたんですが、どこかのマイナーバージョンアップで急に表示されなくなってしまいました。2025でも使えません。モリサワに相談したところ「こちらではどうしようもないのでAdobeさんに相談してください」とのことでした。ちなみにMonotypeの和文バリアブルフォントは問題ありません。ご対応お願いします。

  6. Text Overflow / Overset (+) Indicators are not shown

    A strange thing is happening with a few of my files. Some text boxes have stopped showing the indicator when clicking off of the text box which has text overflow. This recently cause me to mistakenly print a file that had text overflowing with no indication. Why is this happening?

  7. 中韓フォントの文字組みを変更してもアキが変わらない

    フォント「思源黑體 TW」の文字組みを「なし」や「行末約物半角」などに変更しても、アキ量が変化しない現象がありました。
    上記現象が発生したバージョンは下記の通りです。

    OS:Windows 10 Pro
    Illustrator CC:V 29.1、V 29.2、V 29.3.1(V 29.2.1、V 29.3は調べてません)
    なお、V 29.0、V 28.7.3 は当該現象は発生していません。

    問題発生時の手順:

    ・スクリプトを使いCSVデータを読み込んで文字情報を取得、文字をイラストに書き込む
    ・文字入力後、フォント「思源黑體 TW」へ変更
    上記どちらでも問題が発生します。

    想定していた結果:
    添付をご参照ください。
     V29.0文字組み「なし」.png
     V29.0
    文字組み「行末約物半角」.png

    実際の結果:
    添付をご参照ください。
     V29.1文字組み「行末約物半角」.png
     V29.1
    文字組み「なし」.png
    この2つの全角、半角のアキが同じ(変化がない)となっております。
    (どれを選んでも「なし」と同じ状態です)

    他のフォント(下記)で試してみましたが、アキ量の変化は確認できました。

    ・源ノ角ゴシック JP
    ・A-OTF UD新ゴ Pr6N L
    ・メイリオ
    ・游ゴシック

    Illustratorフォーラムにも投稿し他の方にもご検証いただいたところ、日本語以外(繁体字、簡体字、ハングル)のフォントで同様の現象が起きているようです。
    また、InDesign20.1(2025)でも同様の現象が起きているようです。

    バグであれば是非ともご対応いただけると幸いです。

  8. Many issues in Illustrator 2025

    Hi everyone,
    I'm experiencing a range of serious issues in Illustrator 2025 when working with AI or PDF files (many of which originate as PDFs and are then converted to AI for editing). Here's a breakdown of what's going wrong:

    ⚠️ Main Problems:

    Error ID: -128 when pasting text
    Every time I try to paste text into a text box—whether copied from a browser, a PDF, or even another Illustrator file—I get an error saying:
    Can't paste the type. ID: -128
    This makes it impossible to replace or update any existing text areas.

    Can't move objects: transformation too large
    When…

  9. 割注指定の文字と通常の文字の間のカーニングおよびトラッキングができない

    「割注で2段に指定した文字」と「通常フォントサイズの文字」の字間をカーニングおよびトラッキングで広げることはできますが、詰めることができません。環境設定でトラッキング「100/1000em」で設定もしています。割注設定している文字の字間は詰めることはできるのですが…。

  10. 2025 Paragraph styles broken opening files created in previous versions

    Opening up previously formated files (2024) with Character/paragrah styles applied is useless in 2025!

  11. Illustrator randomly substitutes fonts even though they are installed (works fine in older versions)

    In the latest version of Adobe Illustrator, I often experience random font substitution issues when opening older files. The fonts are properly installed in my system, but Illustrator does not recognize them correctly.

    For example, if I copy the same AI file 10 times and open each copy, Illustrator displays different random font substitutions each time. However, when I open the same files in an older version of Illustrator, the fonts display correctly without any issues.

    This indicates that the problem is not caused by missing fonts, but rather by how the new Illustrator version handles font data in older…

  12. 特定のテキスト状態のファイルを開くと旧バージョンで保存されたファイルと誤検知される

    Windows11(macOSでも発生すると思われる)
    Illustrator ver.29.0

    再現手順
    1.新規ドキュメントを作成し文字ツールでポイントテキストを入力する。
    2.1行目を36pt、2行目を10ptで指定する。
    3.Illustrator2020形式でファイルを保存して閉じる。
    4.保存したファイルを開くと「このファイルには旧バージョンのIllustratorで作成されたテキストが含まれます……」のダイアログが表示される。変更を確認しても文字のずれなどは見受けられない。

    期待する結果
    ver.29で保存したドキュメントを開く時にダイアログが表示されない。

    実際の結果
    特定のテキスト構成にて旧バージョンで作成されたドキュメントと正確でないダイアログが表示される。
    おそらく誤検知だと思われます。

  13. Center Vertical Alignment for Area Type becomes Top when Every-Line composer is used

    Take a look at the GIF attached.
    When vertical alignment is set to Center, it works only for Single-line composer. When Every-line composer gets chosen, the alignment becomes Top instead.

    And please rename the option finally — it should be VERTICAL alignment, not horizontal: http://illustrator.uservoice.com/forums/601447/suggestions/45711817

  14. The entire document fails due to the use of area text linked to different pages. Text is lost, the file freezes, won't save, or is stuck

    Mi computador es un MacBook Pro 2022 - Chip Apple M2 - MacOs Sequoia 15.5, pensaba que era un error del Mac por lo que formatee el computador y volví a instalar la suite de adobe, pero no, el error sigue, fue a partir de la actualización hecha después del sábado 28 de Junio. Desde allí el ilustrator presenta diferentes errores que detallaré a continuación:

  16. 29.7.1アップデートにおけるテキスト入力について

    半角入力では問題なく行えますが、日本語の入力時にリアルタイムで反映されず、画面左上で文字が表示され、Enterを押すと入力されるという仕様になっていました。(添付画像参照)
    また、以前のバージョンではAlt + 右 / 左向き矢印キーでカーニングできていましたが、出来なくなりました。
    改善していただきたいです。

  17. Cmd+Opt+Shift+M Erases Text

    OBSERVATION
    The keyboard shortcut Cmd+Opt+Shift+M will open the Character Window and highlight the current font, however this exceptionally incredible time saving shortcut works only if the text is selected and not highlighted.

    While the text is highlighted, performing the Cmd+Opt+Shift+M shortcut, simply erases the highlighted text.

    EXPECTED RESULTS
    The mechanics of this shortcut, many versions ago, performed the expected function, whether the text was highlighted or selected.

  18. Embedded font previews get substituted when pasted as a vector smart object in Photoshop

    In some case, when opening the files, the app does not inform there are missing fonts. They're still displayed like the font is already installed in system. When I copy and paste into Photoshop (as vector smart object), the text is replaced by other fonts automatically without any announcement.

  19. Illustrator sometimes reports the font is not installed but then finds it on its own

    Boa tarde, há uns dias abri um documento que dizia que o tipo de letra estava ausente e hoje ao abrir dizia que já tinha o tipo de letra utilizado naquele texto. Sendo que não instalei a fonte nem passei nenhuma ficheiro da mesma de um pc para o outro, podem dizer-me se isto é normal ou se há algum bug no vosso programa?
