Mystery French Doll Who Am I?

Who is this unknown doll, purchased in Paris, France in approximately 1976?

Help is needed to identify a doll that was purchased in Paris, France in approximately 1976.  The above image is an artist's rendition based on a description provided by the former owner.  Additional information, which hopefully might help lead to the doll's identification, is shared below:

Height: Estimated 5 to 6 inches/13 to 15 cm. Taller than Strawberry Shortcake but shorter than Barbie.
Physique: Proportions are childlike. More like a toddler than a baby or adult doll. Chubby, kind of cherubic.
Where bought: Paris, France at a doll store. Bought brand new. Unsure where manufactured. Bought in the late 1970s, likely around 1976.
Material: Unsure of what material the doll was made of, but the former owner thinks it was plastic but a softer kind of plastic [vinyl or rubber, maybe]. It had a firm (not soft or cloth) body. Its legs and arms moved, but not at the joints (knees or elbows). It was hardy (former owner played with it pretty nonstop for two to three years).
Hair: Short, black curly hair with big roller curls… (2-3 inches in diameter but sitting close to the head).
Mouth: Very neutral/closed mouth with red lips.
Eyes: Hazel eyes with some orange-ish [amber]. Says material for eyes was kind of translucent - light would get into the pupils. Stiff eyelashes that were not separated. Had "sleepy eyes" that closed when she laid down.  She thinks the eyes could be plastic.
Skin color: As pictured in the drawing.  Described as "somewhere between Angela Bassett and...probably Angela Bassett slashTaraji P. Henson."
Clothes: The outfit she came in (pictured) was likely a blue schoolgirl dress with a Peter Pan collar. Thinks it was blue but could've been pink. Puffy sleeves. White panties underneath.
Additional important details: Former owner called the doll Zoe (or "Zoey"), but she doesn't know if that was the name of the doll or whether she gave it that name. She thinks it also came with a trunk, with tiny hangers and one change of clothes. The trunk had a bar inside so you could hang up the clothes.

Note that while the doll was purchased in Paris, France, it was not necessarily made there. The former owner says some of the dolls from Unica Company look similar to Zoe.   This Pinterest board is devoted to Unica dolls, a Belgium doll company.

Below are additional photos of dolls that look similar.

Doll on left looks similar to the mystery doll.

In the photo of these two dolls, the doll on the left looks similar but former owner's doll was better dressed and had a more neutral facial expression.

Doll in blue looks similar to Zoe

The former owner thinks the above doll in the blue dress is super similar but she says Zoe had a more neutral face, not as cheerful.  [The doll in blue looks like a doll made in Italy.  So, Italy, France, Belgium or another country in close proximity to France could be the country of origin of the doll's manufacturer.]

This link to the 1974 doll offerings in a French catalog shows a blonde doll in a group of dolls labeled 1.  That doll is 17 cm, slightly taller than the mystery doll.  The same sculpt and body appear to have been used in 1976 for a dark-skinned doll dressed in islander attire.  Could this be the doll that might have also been dressed in a blue schoolgirl-type dress?
