Abstract

This TIP extends the string trim, string trimleft, and string trimright subcommands to function properly with non-roman writing systems by adding non-ASCII space characters to the default list of characters to be trimmed.

Rationale

By default string trim and its single-sided variants remove ASCII whitespace characters. Some writing systems use other whitespace characters. Adding these characters to the default list will extend the Unicode-friendliness of Tcl.

The characters proposed to be added are:

U+1361  ETHIOPIC WORDSPACE       
U+1680  OGHAM SPACE MARK
U+3000  IDEOGRAPHIC SPACE
