StringWriter is a program that allows you to patch strings in the raw Wii U memory. This is a project that was created with an educational purpose in mind and for helping a friend.
This program can read the Wii U memory in 3 forms; ASCII, Byte, and Unicode. You can easily edit your ASCII or Unicode text and convert them to byte for easy conversion and injection.
Bytes between \00 - \1F are automatically nulled as \00 when converting from Byte to ASCII/Unicode, since it's nature can't be easily handled. Thus handle this with care, converting ASCII/Unicode to Byte with nulled bytes (¶) will convert some of the data to \00s, and accuracy is lost. Possible lost bytes before the conversion can be visible on the text with the pilcrow sign (¶).
Pressing the Apply button will inject only the Byte data. To inject ASCII/Unicode, convert them to Byte first. Also, injecting the data only injects the length of the bytes in the textbox, so the Byte Length:, value on the left of the form, does not apply for injecting, but only for reading. However, Byte Length: does apply to the Apply 0s within range button.
When reading and then modifying the data, it's recommended to match the Current byte length and the Read byte length before injecting the data. Without proper care, you will shift the data and inject it improperly.
ASCII - Represents a character/letter from the American Standard code, relative to the byte value. The size of each ASCII character is 8 bit (aka bytes with 2 digits).
Byte - Represents a numerical value with base 16, instead of the common base 10. Sizes of bytes can vary from 8 bit to 32 bit on the Wii U.
Unicode - Represets a character like ASCII, but the size of each character is 16-bit instead (bytes with 4 digits). The bigger size is to accomodate the support for all languages and special characters.
Also, In most cases the Wii U uses ASCII for most ram mods. Unicode is likely used for only game texts instead.
