Hello,
ext/mbstring is very useful, but from my point of view, some functions
are missing.
I would like to propose the addition of the following functions.
mb_append($str, $piece) and mb_prepend($str, $piece):
To add a $piece to, respectively, the end and the start of $string. It
should consider the text direction, e.g. if $str is Right-to-Left,
mb_append() will add $piece to the end, so the left, of $string.
concat($str, $piece):
If mb_append() and mb_prepend() are too hard to understand by users,
concat() would be pretty much simpler and will act in the same way.
mb_pad($length, $piece, $end):
Pretty much like strpad but with multi-bytes considering.
Note that, like mb_append and mb_prepend, we do not speak about left and
right, but start and end.
mb_get_direction($str):
Return LTR or RTL. For one char, it is “easy”. For a string, it is more
complex because we can have embedding directions (a string with many
directions).
mb_get_char($code) or mb_chr($code):
Get Unicode character from a code-point/decimal value representation.
mb_get_code($char) or mb_ord($char):
Get code-point/decimal value representation from of Unicode character.
Finally, it would be great if mb_substr() could consider text direction
(or create a new dedicated function?). For example, mb_substr($str, 0,
1) will return the first char from the start (and not the left as it is
implemented now).
I think it could help developers to create nice libraries without
requiring a lot of skills in Unicode.
Thoughts?
Best regards :-).
