"## Benchmark of islower() using Base and utf8proc-- UPDATE 2\n",
"Changes: \n",
"* added mojibake_islower(String) based on a C function provided by @stevengj\n",
"* Revised islower_utf8proc() to use a hacked version of category_code(c) which omits the line `cat == 0 ? 30 : cat`.\n",
"* Revised test of islower(Char) using shuffled array of Char. \n",
"* dropped PCRE as it does not work well with Char and libmojibake is the preferred path.\n",
"\n",
"### Updated Findings for test functions, as tested:\n",
"* For islower(Char) run against shuffled Char arrays, islower_base is just a hair faster than islower_utf8proc\n",
"* For islower(String), islower_utf8proc is 3-4x faster than islower_base\n",
"* The discrepency between islower(Char) and islower(String) is probably due to the inefficiency of the all() function used in the Base version of islower(String)."
