Description:
Every time when the argument includes the German letter "ß" (sharp s) in the first word, the second word omits its second letter and there is a double space between the first and second word.

Example:
B2: "SCHIEßER THOMAS"
B3: =PROPER(B2)
Result in B3: "Schießer  Tomas"
Correct result should be: "Schießer Thomas"

Note: it is always the same wrong result (one additional space + the second letter in the second name is omitted), regardless of the position of the letter ß in the first name.

Steps to Reproduce:
1. in cell B2: "SCHIEßER THOMAS"
2. in cell B3: =PROPER(B2)
3.

Actual Results:
"Schießer  Tomas" (note the double space

Expected Results:
"Schießer Thomas"


Reproducible: Always

Additional Info:
its only with the german special letter ß. The letters ä, ö, ü give correct results.
