tools directory include files are not added when the user uses diacritic in username

[tlapik123]

Basically what the title says.

When I use a profile that has diacritic in the name only the
c_cpp_properties.json:

"includePath": [
"C:\\Users\\kód\\AppData\\Local\\Arduino15\\packages\\arduino\\hardware\\avr\\1.8.6\\cores\\arduino",
"C:\\Users\\kód\\AppData\\Local\\Arduino15\\packages\\arduino\\hardware\\avr\\1.8.6\\variants\\standard"
]

are in list.
If I use one without diacritic I get this:
c_cpp_properties.json:

"includePath": [
"C:\\Users\\username\\AppData\\Local\\Arduino15\\packages\\arduino\\hardware\\avr\\1.8.6\\cores\\arduino",
"C:\\Users\\username\\AppData\\Local\\Arduino15\\packages\\arduino\\hardware\\avr\\1.8.6\\variants\\standard",
"c:\\users\\username\\appdata\\local\\arduino15\\packages\\arduino\\tools\\avr-gcc\\7.3.0-atmel3.6.1-arduino7\\lib\\gcc\\avr\\7.3.0\\include",
"c:\\users\\username\\appdata\\local\\arduino15\\packages\\arduino\\tools\\avr-gcc\\7.3.0-atmel3.6.1-arduino7\\lib\\gcc\\avr\\7.3.0\\include-fixed",
"c:\\users\\username\\appdata\\local\\arduino15\\packages\\arduino\\tools\\avr-gcc\\7.3.0-atmel3.6.1-arduino7\\avr\\include"
]

It seems like the code for including the bottom 3 is different since they are all in lowercase(?).

Not having these includes in intellisense means it can't see the libc which causes squiggle include errors (the verify works fine).
#include errors detected. Please update your includePath. ...
