Named Constants

---

Named constants allow you to use a descriptive name for a character, instead of its code. To define a named constant, use store(charname) charcode. When you wish to refer to the code, use either outs(charname) or $charname.

The dollar referencing can only be used with named constants. You cannot use it for stores that have more than one character in them, or for keys or other non-character stores. Named constants are supported for all Unicode characters including BMP and SMP (above plane 0).

Named constants can also be loaded from a file with the &includecodes system store. For instance, the Unicode Character Names can be used by referencing unicodedata.txt. The format of this file is documented in the &includecodes documentation.

Hangeul syllables are predefined named constants, with the following pattern:

$HANGUL_SYLLABLE_<initial><vowel><final>

• initial can be G, GG, N, D, DD, R, M, B, BB, S, SS, J, JJ, C, K, T, P, H, or empty
• vowel can be A, AE, YA, YAE, EO, E, YEO, YE, O, WA, WAE, OE, YO, U, WEO, WE, WI, YU, EU, YI, or I
• final can be G, GG, GS, N, NJ, NH, D, L, LG, LM, LB, LS, LT, LP, LH, M, B, BS, S, SS, NG, J, C, K, T, P, H, or empty

This follows the algorithm documented on Wikipedia.

Example

store(CCedilla) U+00E7
+ [RALT K_C] > $CCedilla
