• File src/OFString.m — part of check-in [13f4c6c678] at 2016-09-12 00:27:14 on branch trunk — Add OF_DEALLOC_UNSUPPORTED macro (user: js, size: 58050) [annotate] [blame] [check-ins using]

To Artifact [4bcce6446e]:

• File src/OFString.m — part of check-in [d9eb7b50b3] at 2017-01-07 00:37:26 on branch trunk — Add of_ascii_{to{upper,lower},is{alpha,alnum}}

  These are independent of the locale and work on the ASCII character set.

  Unlike the C ones, these are 8-bit safe, meaning if a character > 0x7F
  is passed, is{alpha,alnum} returns false and to{upper,lower} returns the
  original character. (user: js, size: 58031) [annotate] [blame] [check-ins using]
