=={{header|Vala}}==
Vala has limited support for Unicode in variable names. This limitation comes from its source-to-source compilation to C.
=={{header|Wren}}==
The rules for identifiers are described [http://wren.io/syntax.html here] - basically they can contain letters, digits (not initially) or underscores but identifiers with leading underscores are reserved for field names.
Although it's perhaps not 100% clear from that description that only ASCII letters and digits are allowed, this in fact is the case as the following example shows.
The error description refers to the bytes in the UTF encoding of 'Δ' which can't appear (outside a string) in a Wren script.
<lang ecmascript>var a = 3
var b = 2
var delta = a - b // ok
var Δ = delta // not ok</lang>
