characters VB6 with W10

Hello Everybody

Hope you all are well and stay safe.
Please, I am contacting you for a puzzling problem I am facing with a VB6 project.
I have searched in past forums without success.
Following is the topic.
In the main part of pc with Windows 10 the software in working properly.
In some of them I am encountering following problem:
Following character
<<°>>
Meaning the degree sign (ascii 167)
1 – in the output screen for VB6, I get that this character is added with
Latin Capital letter A with circumflex
<<Â>> (ascii 142)
Meaning, instead than
<<°>>
I get
<<°>>, meaning both characters

2 – when I print the output with a Microsoft pdf printer, I get that
Following characters are added
<<½>> (ascii 171 )
<<¿>> (ascii 168 )
<<î>> (ascii 140 )
Meaning, instead than
<<°>>
I get
<>>


Again, my problem is that this is occurring only in one pc with W10, while in the others all works properly.
Please can anybody give me some hints concerning this topic ?

Thanks in advance, Regards and stay safe
