> Ada String is basically char array

Worse, the built-in Unicode strings are arrays of Unicode scalars, effectively UTF-32 in the general case. There's no proper way to write UTF-8 string literals AFAIK, you need to convert them from arrays of 8, 16 or 32 bit characters depending on the literal.

How is the internal representation an issue? Java string are utf16 internally and it's doesn't matter how you write your code nor what's the targeted format.

It's an issue because there's nothing internal about the representation in Ada: They're regular arrays of Character/Wide_Character/Wide_Wide_Character, and string literals have different type depending on the width required to represent it as such.

Also, string representations very much matter if you're coding with even the slightest amount of mechanical sympathy.
