I prefer to keep my scope very tight when posting on Stack Overflow.

My focus was purely on enabling character range syntax for native functions
with character mask parameters.  My understanding of character masks in PHP
requires single-byte characters and no meaning to character order.

When strtr() is fed two strings, they cannot be considered "character
masks" because the character orders matter.

If extending character range syntax to parameters which are not character
masks, I might support the feature for strtr(), but ensuring that the two
strings are balanced will be made more difficult with ranged syntax.
strtr() will silently condone imbalanced strings.  https://3v4l.org/PY15F
