Matlab R2022a still doesn't allow non-ASCII characters in identifiers.

According to their documentation:
https://www.mathworks.com/help/matlab/matlab_prog/variable-names.html

> A valid variable name starts with a letter, followed by letters, digits, or underscores.


And
https://www.mathworks.com/help/matlab/ref/function.html

> Valid function names begin with an alphabetic character, and can contain letters, numbers, or underscores.


I didn't find where they document valid names for scripts. But the rules seem to be the same as for variables and functions.

Does

source ("schläfli")

work for you?

You can only use ASCII names for function or script names in Octave is because the names have to be valid identifiers in the language and valid identifiers are limited to the pattern

[_$a-zA-Z][_$a-zA-Z0-9]*

Does Matlab allow identifiers to have additional non-ASCII characters?  If so, is that a recent change?

Request that Octave kindly support Unicode file names. File schläfli.m calculates Schläfli symbols (https://en.wikipedia.org/wiki/Schläfli_symbol). Calling it inside Octave causes an error:

>> schläfli
error: parse error:

  syntax error

>>> schläfli
        ^

But calling it outside Octave is OK.

octave schläfli.m
( normal output from schläfli.m )
-verbatim+

Unicode file names are accepted by gcc, g++, Python, etc.
