Why is the Insert:Special_character glyph an Ω symbol. Ω is not available as a special character, nor is any of the Greek alphabet for that matter. I just started an edit in VE on the basis that I would be able to do this and then find I cannot complete it. How annoying.
Topic on VisualEditor/Feedback
It's not an uncommon choice for that icon: it's the same symbol Google Docs uses, for example. Which character were you looking for? The list of the available ones is customizable on a per-wiki basis. Best,
I was looking for lowercase lambda, but that is beside the point. The whole greek alphabet is needed, along with all the accents and breathings. How am I supposed to write electrical engineering articles without Ω? It is the symbol for ohms. Oh, and by the way, Google Docs does have Ω.
Are you saying the available symbols are controllable by local admins? If so, where? Another consideration, if all the symbols currently available in the standard editor were to be put in VE, would they all have to go on the same page? Currently, they are spread across several pages through a drop down menu. Google docs, which you seem to like so much, does the same.
The character inserter is not in its final form yet (there are previous discussions about it on this page as well). There's more information at VisualEditor/Special characters. HTH,
I have tried to make the common problem of misformatted changes be more obvious in the help page.
This is called a false promise.
