Title: Intelligent Character Replacement question Last modified: November 20, 2021 --- # Intelligent Character Replacement question * Resolved [H&S-Team](https://wordpress.org/support/users/hackespitze/) * (@hackespitze) * [4 years, 7 months ago](https://wordpress.org/support/topic/intelligent-character-replacement-question/) * First, thanks a lot for a very helpful plugin! * In our project, we auto-create Image Titles and Alt-Text from image-file-names. We use _custom diacritic word replacements_ to re-establish German Umlauts and special character. * As our list is growing quickly, I would like to know whether it also works with partial matches. Say I would like to re-establish the letter ä, whenever the string _aermel _is found. * Instead of explicitly adding every possible word and case (aermel, aermeln, aermels, spitzenaermel) … is there a way to add just the relevant subset of the word? * In my sample, the snippet *aerm* would do – and it also worked for _laerm_ and _waermflasche_. Hence – we could serve all cases with a far shorter list. - This topic was modified 4 years, 7 months ago by [H&S-Team](https://wordpress.org/support/users/hackespitze/).

(Or if you’ve already uploaded all the files, a database search & replace.). This would allow for subsequent manual fixes to incorrect replacements. * Thread Starter [H&S-Team](https://wordpress.org/support/users/hackespitze/) * (@hackespitze) * [4 years, 6 months ago](https://wordpress.org/support/topic/intelligent-character-replacement-question/#post-15110601) * Thanks for your reply! I now understand that limiting the tool to full words was a deliberate design decision. I’m curious – Have you actually tested failure rate at scale? Only considering the long explicit replacement list I already have, turning Umlauts in German language from ue, ae and oe to ü, ä and ö should work robustly. None of the list-entries we have so far would cause an error. * An _inverted list_, which holds all exceptions to transcription rules (_Carmen McRae, Dr. Oetker, Menuett, Hugo Strasser_) should be greatly shorter. * @Uploadfilter: We by all means need image names without umlauts and other German language characters, as these cause trouble in our Import Pipeline. While naming images offline, we therefore have removed all Umlauts, etc. As we still forgot a few, our Importer went haywire. For that reason, a script now skips wrongly named assets. * What we want is recreate the special characters with image file-names as input** while leaving image-names unchanged**. Search and Replace could work – but one would not want to run this manually, each time, when uploading assets. * Having these special characters right could give a competitive edge in Image SEO in E-Commerce for German language markets. For this to work, however, one needs to re-establish proper names, before assets get indexed by search engines. * Plugin Author [pepe](https://wordpress.org/support/users/pputzer/) * (@pputzer) * [4 years, 6 months ago](https://wordpress.org/support/topic/intelligent-character-replacement-question/#post-15110727) * By “renaming” I meant the names of the attachment objects in WordPress, not ( necessarily) the actual filenames. All this can be done with upload filter hooks. In any case, you can add custom fixes using the [wp-Typography API](https://github.com/mundschenk-at/wp-typography/blob/master/includes/wp-typography/typography/class-custom-token-fix.php#L96), it is just not something I would recommend. However long your exception list is, it will always miss some words. * Thread Starter [H&S-Team](https://wordpress.org/support/users/hackespitze/) * (@hackespitze) * [4 years, 6 months ago](https://wordpress.org/support/topic/intelligent-character-replacement-question/#post-15110897) * Thanks again :o) I will discuss the options you propose with our developer. * While our project hasn’t gone live yet I’m very happy how much better text looks on the staging site with your WP-Typography. Great that you make this available. 👋 * Plugin Author [pepe](https://wordpress.org/support/users/pputzer/) * (@pputzer) * [4 years, 5 months ago](https://wordpress.org/support/topic/intelligent-character-replacement-question/#post-15246444) * Hi [@hackespitze](https://wordpress.org/support/users/hackespitze/), do you have more question or can we consider the issue resolved? * Thread Starter [H&S-Team](https://wordpress.org/support/users/hackespitze/) * (@hackespitze) * [4 years, 5 months ago](https://wordpress.org/support/topic/intelligent-character-replacement-question/#post-15268170) * Hi [@pputzer](https://wordpress.org/support/users/pputzer/), please excuse my belated reply!
