Dear Maintainer,

Yes good:
        $ cat f1
        row1    f1      1
        urow1   f1      2
        $ cat f2
        row1    f2      1
        urow2   f2      2
        $ join f? -t '  '
        row1    f1      1       f2      1

Not good:
        $ cat f1
        row1ąf1ą1
        urow1ąf1ą2
        $ cat f2
        row1ąf2ą1
        urow2ąf2ą2
        $ join f? -t 'ą'
        join: multi-character tab ‘ą’

Compare manual:
        -t CHAR use CHAR as input and output field separator

Compare POSIX.1-202x/D3, XCU, join, OPTIONS:
        −t char
                        Use character char as a separator, for both input and 
output. Every appearance of
                        char in a line shall be significant. When this option 
is specified, the collating
                        sequence shall be the same as sort without the −b 
option.

Please try coreutils 9.5 which has improved multi-byte char support in join
