bidi_strip

bidi_strip("\x{2066}/\x{2068}dev\x{2069}/\x{2068}sdb1\x{2069}\x{2069}");
# -> "/dev/sdb1"

Remove BiDirectional Text formatting characters from a string.

In Right-to-left languages such as Arabic and Hebrew, /dev/sda1 looked like dev/sda1/ so we fixed it in YaST by adding BiDi control characters. https://en.wikipedia.org/wiki/Bidirectional_text#Explicit_formatting

But if you look for "/dev/sda1" in partitioner tables, it is no longer there unless you apply bidi_strip first.
