 I went in to edit a post I made yesterday (link below), but for some reason the edited post isn't showing. Instead it lopped off most of the original text, and that's all that's visible. Clicking on the edits links at the bottom of the post show the original text, except that the microfarad symbol (created by using the Alt. key and the numbers 0181) have been replaced with a question mark in a black diamond.

Is it the alternative symbol causing the text to disappear? This is a new one on me.


Thanks

 Yes, you guessed correctly.

This is one of these areas where we should have left well enough alone. Some time ago, we converted the database to UTF-8 which is one of those great relatively new things. Afterward, we found problems with 8 bit characters and differences between the Windows and ISO character sets and translations along with some platform issues. We've done some workarounds for the common characters, but you found another one.

So, when one of the characters gets saved to the db, it truncates the post after that character. Because the posts also get saved in an html format on disk, you can see the old post in your edits and that character gets shown as the funny black diamond whereas the messages you see are generated from the db where it is truncated.

You can still edit the post and copy the original from a saved edit version and replace the diamond character with a non-correct 'u' for the microfarad symbol.

The new responsive code base that we're working on now will have a re-written post routine and one of the things we're going to try to do is to get that bug licked completely.

 My original reply, using the correct microfarad symbol, posted correctly. It's when I went to edit it today that the trouble started.

I followed your suggestion, substituting 'u', and my last edit posted correctly, so thanks.

Will the new code be a blanket fix, or will you need to know each individual character we use? I ask, because another one I use occasionally is Alt. 0186 which creates the "degree" symbol.

Thanks again, Rod.

 I wish I was expert enough in this area to give you an absolute answer. Our objective is surely to solve it. OTOH, it may not be that easy.

 I was simply curious.

Thanks for keeping the engine running and the doors open.
