Scheme Request for Implementation 175,
"ASCII character library,"
by Lassi Kortela,
has gone into "final" status.

The document and an archive of the discussion are available at

Here's the abstract:

This SRFI defines ASCII-only equivalents to many of the character procedures in standard Scheme plus a few extra ones.  Recent Scheme standards are based around Unicode but the significant syntactic elements in many file formats and network protocols are all ASCII. Such low-level code can run faster and its behavior can be easier to understand when it uses ASCII primitives.

Here are the diffs since the most recent draft:

Many thanks to Lassi and to everyone who contributed to the discussion of this SRFI.
