Unicode characters display?

Ronan — Tue, 10 Nov 2026 11:54:18 Z

How can I input and display unicide characters?
then I would like to add the characters to a special pallet.

restart;
UTF8(U + D7CF);
Error, invalid input: UTF8 expects its 1st argument, s, to be of type string, but received U+D7CF
UTF8("U+01 D7CF");
                          "U+01 D7CF"

"U+01 D7CF";
                          "U+01 D7CF"

U + D7CF;
                            U + D7CF

unicodeexamples
U+01 D7C9 
U +01 D7CF
U +01 2540
U +01 2541
   U list unicode examples + D7C9 U + D7CF U + 2540 U + 2541

Is this a bug in solve?

nm — Tue, 10 Nov 2026 07:41:35 Z

Is this a bug in Maple? it gives error in Maple 2026.2 and also Maple 2025.2

restart;

ode:=-1/diff(Y(X),X)^3*diff(diff(Y(X),X),X)+4*X = piecewise(0 <= Y(X) and Y(X) < Pi,0,Pi <= Y(X) and Y(X) < 2*Pi,10,2*Pi <= Y(X),0);

solve(ode,diff(Y(X),X$2))

workaround is to use isolate instead of solve or Solve:

But why solve fails just because RHS is piecewise ?

Wanted to check before sending bug report in case it is by design.

Why does Maple update fail due to open programs?

Frank DiJoseph — Mon, 09 Nov 2026 15:57:21 Z

I just opened maple to use it, and I receieved a notice that an update was available. I proceeded with the update and it failed to install, complaining that "open programs" needed to be closed. There were no open programs so I opted to have the installer "ignore" the warning. However, it would not continue and it gave a list of two programs that were in use (even though I had closed Maple). This is a snapshot of the warning.

It appears that the update may have completed as the maple version that appears during startup is 2026.1. However, the program is very slow to open a new document (I have to click on the "New Document" button several times before it response) and very slow to close.(I have to click on the "X" icon (upper right of top menu) before it will close.

Any help would be appreciated.

Regards,

Frank DiJoseph

Document Introspection Techniques

OptimusMaplePrime — Thu, 29 Oct 2026 17:20:53 Z

Question

What are the best techniques for performing introspection in Maple Documents?

Background

I would like to use the content within a Maple Document (.mw) as input to calculations and operations within the same document. I am aware of the DocumentTools Package, but it seems that needs to open a copy of the current document to perform operations and is dependent on the current document being saved to disk rather than working with what is already in memory. What techniques are available to work with the document's data model and content within the document, such section headings, section structure, and paragraph text content - as opposed to just the variables that have been defined?
