This feature lets foot combine e.g. "a\u0301" to "á". We first check if the current character (that we're about to print) is a combining character, by checking if it's in one of the following ranges: * Combining Diacritical Marks (0300–036F), since version 1.0, with modifications in subsequent versions down to 4.1 * Combining Diacritical Marks Extended (1AB0–1AFF), version 7.0 * Combining Diacritical Marks Supplement (1DC0–1DFF), versions 4.1 to 5.2 * Combining Diacritical Marks for Symbols (20D0–20FF), since version 1.0, with modifications in subsequent versions down to 5.1 * Combining Half Marks (FE20–FE2F), versions 1.0, with modifications in subsequent versions down to 8.0 If it is, we check if the last cell appears to contain a valid symbol, and if so, we attempt to compose (combine) the last cell with the current character, using utf8proc. If the result is a combined character, we replace the content in the previous cell with the new, combined character. Thus, if you select and copy the printed character, you would get e.g. "\u00e1" instead of "a\u0301". This feature can be disabled. By default, it is enabled if the utf8proc library is found, but can be explicitly disabled, or enabled, with 'meson -Dunicode-combining=disabled|enabled'.
