I do not know whether it is a bug in the EmEditor core or in its plugin engine or even it is possibly a defect in the highlighter definition (I just cannot dedicate time learning it), but I’ll post here this as my question to rule out any doubt:
When I write SQL code in EmEditor I get no strings highlighted if they span more than one line and this is misleading developing code like that.
I am showing examples next here for SQL Server Management Studio http://imageshack.us/photo/my-images/221/sqlcodeinssms.png/ that does this properly versa EmEditor http://imageshack.us/photo/my-images/715/sqlinemeditor.png/ that unfortunately does not.
