Special Language characters are not shown on MD4-7

jan 2 years ago in IQANdesign updated by Gustav Widén (System support) 2 years ago 3


Polish (special) characters are not shown on our test display screen, see attachment.

No problems when using IQAN Simulate

On this MD4-7 display have been downloaded several applications, never noticed this problem before.

Only recently, as I am developing a new application !

Please let me know why, how or what to do. 

Thanks in advance,


Software version:

Serialnr. MD4:      1634280065


To display all of the Polish alphabet on the MD4, you will need to set a different font than the Default font.

It is the same as with for example the Russian alphabet. 

To try it out with a commonly used font, test for example Tahoma. 

Hello Gustav,

After changing the default font for Polish into Tahoma, the problem is solved

Thanks for quick reply.

Some research on previous applications learned me that the Polish font was Arial and also not default.

I can not remember I ever changed the Polish font, maybe previous was Arial the default for Polish ?

Never the less, I can continue

Thanks again
