Abstract

This TIP proposes to rename "string is unicode" to "string is transferable".

Background

TIP 597 introduced "string is unicode". Please refer to this TIP for a description. TIP 652 proposes to remove this class from the "string is" command.

On a core list discussion, it was expressed:

"string is unicode" may have value
the class name "unicode" is miss-leading.
the more appropriate class name "transferable" was proposed.
a more generic command to get the list of all unicode character classes included in a string may superseed this command.
the use of the ICU library may be the next step for those tasks.

Rationale

The current class name "unicode" is seen as miss-leading, see TIP 652.

The name "transferable" suggests, that the string is tested to be ready for a transfer to an external resource like a file or data base.

It is proposed, that this TIP is voted together with TIP 652.

Specification

Rename:

string is unicode ?-strict? data

string is transferable ?-strict? data

If TIP 652 is accepted, this TIP is automatically widthdrawn.

Rename the directly connected C API function

Tcl_UniCharIsUnicode

Tcl_UniCharIsTransferable

The manual page adds a phrase like: "The purpose is to test a string to be transfered to an external resource."

Implementation

The implementation of this TIP is in the Tcl tip-685 branch.
