# Editing formulas with Unicode symbols

Should the questions with Unicode symbols in formulas be edited?

I'm asking this based on this question. Look in the source code to see what I mean.

• No! Unicode is the future... – Fabian Dec 16 '12 at 20:11
• What's wrong with having Unicode characters in posts? I use them all the time in my posts. (I don't use Unicode math symbols but rather symbols like “ ” — « ».) – Yury Dec 17 '12 at 1:03
• I have a pretty low threshhold for editing posts—I go around adjusting the spacing and the heights of the parentheses in formulas—but even I wouldn't bother to replace a literal ε with \epsilon. – MJD Dec 17 '12 at 2:30
• If it looks good, I don't see why we should bother. The only case I can see for editing is if the OP used literal ε one place and \epsilon another, and the two don't look the same.... – Willie Wong Dec 17 '12 at 9:43
• I like using unicode math symbols. I find it easier to "scan" the code with unicode symbols and I use hotstrings to type them fast. Which problem could unicode symbols give ? – Kasper Dec 17 '12 at 14:58
• Perhaps @m0nhawk should say what problem he or she thinks is being addressed here? – MJD Dec 17 '12 at 17:50
• Not sure if it's related but it seems that Firefox has some trouble with one of the fonts it uses for mathematical Unicode characters. – draks ... Dec 18 '12 at 19:28
