<i18n dev> RFR: 8232161 Unexpected 1-way trip conversion entries on MS950 charset

[Ichiroh Takiguchi]

Hello.

I have no idea about compatibility impact.

But according to ftp://ftp.unicode.org/Public/12.1.0/ucd/UnicodeData.txt
These are BOX DRAWINGS characters.

2550;BOX DRAWINGS DOUBLE HORIZONTAL;So;0;ON;;;;;N;FORMS DOUBLE 
HORIZONTAL;;;;
255E;BOX DRAWINGS VERTICAL SINGLE AND RIGHT DOUBLE;So;0;ON;;;;;N;FORMS 
VERTICAL SINGLE AND RIGHT DOUBLE;;;;
2561;BOX DRAWINGS VERTICAL SINGLE AND LEFT DOUBLE;So;0;ON;;;;;N;FORMS 
VERTICAL SINGLE AND LEFT DOUBLE;;;;
256A;BOX DRAWINGS VERTICAL SINGLE AND HORIZONTAL 
DOUBLE;So;0;ON;;;;;N;FORMS VERTICAL SINGLE AND HORIZONTAL DOUBLE;;;;

I don't think it was used as valuable data until now.
I think it's necessary to evaluate compatibility.

To Sato-san,
if you have any question and suggestion, please let me know.

To other reviewers,
please let me know if you have any question and concern.

Thanks,
Ichiroh Takiguchi
