+## FAQ
+### `(guillotine)` Q: How can I keep my string(s) from being decapped?
+A: There are a number of ways to make a string "fixed case" so that it will not be decapitalized when displayed:
+
+C strings: Replace the `_` with `_C`:
+```c
+// _C = fixed (C)ase string!
+const u8 gText_IDNumber[] = _C("IDNo.");
+```
+ASM strings: Replace `.string` with `.fixstr`:
+```arm
+gText_SavingDontTurnOff::
+    @ Lasts until the string terminator '$'
+	.fixstr "SAVING…\n"
+	.string "DON'T TURN OFF THE POWER.$"
+```
+You can fix-case/unfix parts of a string like so:
+```arm
+	.string "{FIXED_CASE}WARNING!{UNFIX_CASE}\p"
+```
+For a placeholder (only the placeholder will be fixed-case):
+```arm
+	.string "{STR_VAR_2_FIXED} was transferred to\n"
+	.string "BOX “{STR_VAR_1}.”$"
+```
+See also the configuration in [text.h](gflib/text.h).
+
+There are also a number of bigram exceptions that will not be decapped: `TV, TM, HP, HM, PC, PP, PM`
