Hi,

 

I tried it on PostgreSQL 13. If you use the Unicode Variation Selector and Combining Character

, the base character and the Variation selector will be 2 in length. Since it will be one character on the display, we expect it to be one in length. Please provide a function corresponding to the unicode variasion selector. I hope It is supposed to be provided as an extension.

 

The functions that need to be supported are as follows:

 

char_length|character_length|substring|trim|btrim|left

|length|lpad|ltrim|regexp_match|regexp_matches

|regexp_replace|regexp_split_to_array|regexp_split_to_table

|replace|reverse|right|rpad|rtrim|split_part|strpos|substr|starts_with

 

Best regartds,
