+/* Notes about safety/randomness:
+ * - Radio data is from nature, so if it's evenly tiled in space, it's random enough, but usually it's not
+ * - A unsafe point is the freq that fetch data is from LCG (from Cpp STL) using time as seed, but should be spread out by later random calculation
+ * - A unsafe point is the init data is still using LCG to generate, but used following methods to spread out:
+ * - - Radio data
+ * - - save a buffer of seeds and generate char by char, this cover all the possible chars combination
+ * - - Rollout with teo seeds and get a final char, this spread out again
+ * - - Hash out the generated password and spread out again if you choose. SHA-512 is proven very spreading out in random space by math
+ * - But still, this isn't meant to become a TRNG generator, don't use at critical/high safety requited/important system, this FOSS has absolutely no warranty

+The purpose of this: when creating an ext app it's address will be changed. But the compiler doesn't know this, so when it optimizes literals it can remove something from one ext app, that is included in the other, to save space.

+So we must use this Language helper that stores the literals in the fw instead of any ext app, so it'll be always available.
