Uppercase A with acute accentBox T-junction pointing up
ASCII 193 is Á on Windows and ┴ in old DOS.
Á (Capital A with Acute) is byte 193 in Windows-1252, Unicode U+00C1. It starts Spanish names like Álvaro and Ángel, and Hungarian and Icelandic use it too (Ábel, Ásgeir). Spanish writers sometimes drop the accent on capitals, but the Real Academia Española is clear that capitals keep it: ÁNGEL, not ANGEL. Its garbled form is nearly invisible. UTF-8 stores Á as C3 81, and 81 has no character in Windows-1252, so Ángel shows up as à followed by nothing, or stops a strict decoder with an error. The HTML entity is Á.
┴ (Light Up and Horizontal) is byte 193 in code page 437, the original IBM PC character set, and maps to Unicode U+2534. It's the tee on the bottom edge of a single-line table or box, where a vertical divider │ (179) comes down and meets ─ (196); ┬ at 194 is its top-edge twin and ┼ at 197 the cross between them. A search for an upside-down T can land here, but for perpendicular lines, or false in logic, the right character is ⊥ (U+22A5), which sits on the baseline instead of filling the cell. In UTF-8 it's E2 94 B4, and the HTML entity is ┴.
#include <stdio.h>int main(void) {/* On Windows (code page 1252) byte 193 is Á.Modern terminals expect UTF-8, so print the code point, not the byte. */printf("\u00C1\n"); /* UTF-8: C3 81 */unsigned char b = 193; /* the raw Windows-1252 byte */printf("%d 0x%02X\n", b, b); /* 193 0xC1 */return 0;}
#include <stdio.h>int main(void) {/* Byte 193 is ┴ only on a console using code page 437(chcp 437 on Windows, or DOSBox). On a UTF-8 terminal thelone byte 0xC1 is invalid and prints as garbage, often �. */putchar(193);/* char is signed on x86, so a plain char holding 0xC1 is -63.Use unsigned char when you compare or index by byte value. */char c = (char)193;unsigned char u = 193;printf("\n%d %d\n", c, u); /* -63 193 *//* Portable: print the Unicode character as UTF-8 instead. */printf("\u2534\n"); /* E2 94 B4 */return 0;}
It depends on the language. Spanish files Álvaro among the A names and only uses the accent to break ties, while Icelandic treats Á as a letter of its own between A and B, so Ásgeir comes after every plain A. Let the database handle it with a language collation, such as utf8mb4_spanish_ci or utf8mb4_icelandic_ci in MySQL.
Use one set of junctions per row type. The top border runs ┌ ─ ┬ ─ ┐, rows are separated by ├ ─ ┼ ─ ┤, and the bottom closes with └ ─ ┴ ─ ┘, with │ between cells. Build every border from the same column widths as the rows, so each junction lands directly under a │.
