LOS TEXTOS EDITABLES EN ILLUSTRATOR DE VERSIONES ANTERIORES NO APARECEN

Just how old is the text?

Text from versions older than CS have to be converted. You should get a warnoing when openoing the documents. The command for doing so is in the Type menu (Legacy text)

Illustrator CS changed the text engine. Text created in versions prior to that may not be compatible. 

You might be able to open the Illustrator file in Acrobat and copy the text from there.

Hello @Rubén28081034nyge,

Sorry to hear about this experience. Would you mind sharing some more details, like the exact version of the OS/Illustrator, whether Illustrator behaves this way with other files, your workflow, and a screen recording of the problem (https://community.adobe.com/t5/illustrator-discussions/screen-record-an-issue-on-windows-amp-macos-for-sharing/td-p/12967727), as suggested by Mylenium so that we can investigate this further?

Looking forward to your response.

Thanks,

Anubhav

Without any info about your system, how the old files were created and in what version and details like fonts and languages we can't really tell you much. You need to be more specific.
