Non UTF-8 characters in source code

[JacobChrist]

Describe the bug Non UTF-8 characters in source code.

To Reproduce Opening the project several error messages like the following appeared:

"uimenu.h" contains unrecognized characters. If this code was created with an older version of Arduino, you may need to use Tools -> Fix Encoding & Reload to update the sketch to use UTF-8 encoding. If not, you may need to delete the bad characters to get rid of this warning.

Following the procedure to Tools -> Fix Encoding & Reload did not resolve the issue.

The code still complies, and this may not be an issue, but its scary because I don't want to brick my working printer.

Expected behavior No errors upon opening the project.

PC (please complete the following information): Windows 10 Arduino IDE 1.8.13 (opps, had .18 in error) Arduino SAM Boards (32-bits ARM Cortex-M3): 1.6.8

**Printer Duo 2.0

Firmware (please complete the following information):

• Branch used [master] 445fa50f8704c0ac70a9d769222763711cc16064
• Version displayed in printer menu Settings/Sytem Version
• Configuration used in configuration.h: Unmodified
• Did you modified the code: No

I tried to copy and past "uimenu.h" code into Notepad++ and convert to UTF-8 then delete and copy back to Arduino IDE, save the file and reopen the project and could not resolve this issue.

the readme mention the arduino version to use, did you read it ?

[luc-github]

anyway you may workaround by disabling Japanese in configuration.h

#define LANGUAGE_JP_ACTIVE 0 // Japanese

Fair enough. I didn't use the same IDE, but it is a 1.8.x flavor and figured it would be okay. The firmware compiles and loads onto my printer just fine. Just wanted to log the issue.

I do not reproduce issue and I have tested the latest which is 1.8.13 , my windows support asian chars, so disabling japanese should remove the problem on your side,
