This is an incredibly resource-wasting problem. Simple text edits on files with lots of text have gone from normally annoying to absolutely hours-wasting.

While it was being approved another issue have risen about this.

If you use variables, create/import a bunch and then you decide to change a font for a text block involved in datasets - you are scrwd:
- change a block font settings
- switch to another dataset
- switch dataset back (or a third one no matter)
you have the initial font in this text block back.

And this is really bad.

Create a text object (area/not area - does not matter). Chose font you want to use (say Font1, bold) and type. Select object afterwards, and set new font for it (say Font2, regular). Text will change it's appearance (as expected). Then select entire text using type tool and then delete it. In this empty text object type a new text. it will appear with Font1 bold style (Font2, regular expected).
Please see screencast attached.

Noticed in the latest version 29.1. Not sure about 29.0.

It may happen and may not. More often it happens. I cant clearly say what exactly triggers this behavior.

Whenever I have a text zone with ANY font, if I input new text, it will ALWAYS output the new text in Arial Bold, regardless of the original text font (whether it's Arial Regular, or some custom font).

This is more than frustrating, it's kind of a blocking issue, since I cannot edit any text without having to manually set again the font for the text zone.

To reproduce:
- Create a text zone, type some text
- Set the text zone to be another font than Arial Bold (you can choose Times New Roman or Futura)
- Edit the text, the new text will be Arial Bold

Expected:
New text should be the same properties as the rest of the text zone

I'm experiencing this as well. I searched for it a few days ago and didn't see this thread but I'm happy to see this is getting some attention. My fonts are changing to other fonts I have been using as soon as I start typing to edit. I am in the midst of some heavy production work where I need to be efficient and this is getting very annoying.

What's happening for me is if I copy and paste text boxes and change it to a new font I'm using, and then edit the text in the text box, it reverts back to the previous font I was using. Or if I create a new text box, edit the text and set the font as I'd like it, as soon as I type anything new into the text box it changes to a different font in my file.

I just saw the temporary fix suggested so I'm trying that now.

This problem is getting annoying. It wastes a lot of time editing those missing glyphs. It’s a problem I haven’t seen in several years.

This was happing to me too with latest update. Very annoying when working with lots of type. But the suggestion of checking off the Glyphs pref Type prefs seems to have fixed it.

I am using Version 29.1 of Illustrator on a Mac.

I want to replace all of Font A in my document with Font B. I use the Find/Replace Font tool to select Font A and hit Change All after selecting Font B. This works as expected and all my text written in Font A turns into Font B.

However, when I try to type anything new in the existing text boxes, all the new text reverts back to Font A. When I try to create a new text box, the font by default uses Font A even if I change it to Font B or any other font.

Hello, j'ai ouvert une discussion aujourd'hui à ce propos. J'ai le même souci et suis d'accord avec Michael Karst, ça n'affecte que les fichiers créé avant la version 29.1
Je ne peux pas revenir à une version antérieure (ce que m'a préconisé un employé Adobe) car je travaille à distance et tous mes collègues ont fait leurs mises à jour. Pourtant aucun d'eux n'a ce souci...

When editing existing text in Adobe Illustrator 2025, the font formatting of the text resets to the default font (Myriad Pro) instead of retaining the original formatting of the text box. This issue persists even when the text box is selected using the Selection Tool (V) before editing. This behavior did not occur in previous versions of Illustrator and disrupts the workflow.

Very annoying glitch isn't it, have we got a solution yet... happens if the text is in a text block or not. Oh and InDesign is on the blink too, workspaces fully playing up.

I don't know what changes have been made to the text in version 29.1, which has caused many text related issues.

It doesn't matter what font I set, it defaults to Myriad bold when I adjust anything in the existing text box. I added a photo that I had adjusted just the measurements in an existing text box. I've force quit, reopened and used different documents, and it keeps happening.

1.) MacOS 14.6.1, Adobe Illustrator 2025
2.) Vorhandenes Dokument öffnen und fehlende Schrift durch vorhandenen Font ersetzen. (Entweder über "Fehlende Schriftarten auflösen" oder auch direkt im Werkzeugfenster "Zeichen". Im gesamten Dokument den Texten eine neue Schriftart zugewiesen.
3.) Die Schriftart ist nun überall ein neuer, vorhandener Font. Optisch sieht alles gut aus, wird auch korrekt angezeigt.
4.) Sobald ich nun etwas am bestehenden Text ändere oder neu dazu eingebe, ist diesen Zeichen wieder der alte, fehlenden Font zugewiesen und muss erneut ersetzt werden.

Same for me. Brand new bug. A lot of work on generative AI that most Illustrator users don't bother, but everyday and simple tools from 1982 falling apart… It's the Adobe we (dis)like, you know.

I am having the exact same issue with Jana Thork Pro changing back to Jana Thork Pro Bold every time I type into a text box that already contained writing in Jana Thork Pro. It's incredibly frustrating. This is happening after having had to update AI and reinstall a bunch of fonts today due to Jana Thork Pro disappearing from all my software despite being 'installed' according to Adobe Cloud. See attached screen recording.

Adobe... The constant bugs are getting ridiculous. Each version is less usable than the one before.

Have updated in the past few days (to 29.1) and am finding fonts are reverting to previously used ones when editing text. It can be a new string of text or an existing one, but it's happening when selecting all type to amend, or even when the cursor is in the middle of two characters of another font. Really irritating!
