Encode text as a 1-D symbol. Returns a table: symbology, text (the
human-readable data, e.g. EAN-13 with its check digit), widths (element widths
in modules, first element a bar, quiet zones excluded), quiet (left, right) in
modules, n_modules (symbol length without quiet zones), edges (cumulative
element boundaries starting at the left quiet-zone edge = 0), values (symbol
character values, Code 128 only) and wide_ratio (two-width symbologies).
symbology: "ean13" (12 or 13 digits; the 13th must be the check digit),
"upca" (11 or 12 digits), "code128" (ASCII 32..126, automatic code sets
B / C; gs1=True puts FNC1 first and maps '\x1d' to FNC1 — GS1-128),
"code39" (0-9 A-Z - . space $ / + %, start/stop * added, optional
mod-43 check with check_digit=True), "itf" (an even number of digits;
check_digit=True appends the GS1 mod-10 check to make the count even).
wide_ratio (two-width symbologies) must lie in [2.0, 3.0].
空の入力(text == "")は ValueError(理由: 符号化する中身が無い)。
拒否(ValueError): 文字列でない、未知のシンボル体系、字種の外の文字、桁数違い、
検査数字の不一致、wide_ratio が [2.0, 3.0] の外。
