String.gsub doesn't work correctly ?

Hi. I recently tried out gsub and figuring how it works, and I ran into a problem. I have a script like this

01local charmap = {
02    ["k"] = 'x',
03    ["kh"] = 'x',
04    ["c"] = 'k',
05    ["c?"] = 'k',
06    ["c!"] = 'k',
07    ["ch"] = 'k',
08    ["cq"] = 'k',
09    ["t"] = 'c',
10    ["tr"] = 'c',
11    ["c"] = 'c',
12    ["ch"] = 'c',
13    ["d"] = 'z',
14    ["g"] = 'z',
15    ["gi"] = 'z',
16    ["r"] = 'z',
17    ["g"] = 'z',
18    ["gi"] = 'z',
19    ["gì"] = 'z',
20    ["gí"] = 'z',
21    ["g?"] = 'z',
22    ["g?"] = 'z',
23    ["g?"] = 'z',
24    ["?"] = 'd',
25    ["p"]= 'f',
26    ["ph"]= 'f',
27    ["n"] = 'q',
28    ["ng"] = 'q',
29    ["nh"] = 'q',
30    ["n?"] = 'q',
31    ["t"] = 'w',
32    ["th"] = 'w'
33}
34 
35print(string.gsub("tieng", ".", charmap))
 View all 35 lines...

but instead of printing "tieq", it prints "tieqw" (look at the character map for reference). Please fix it for me. Thanks in advance.

When I tested, it printed what it was supposed to: wieqz.

The first letter, t was matched and replaced with w.
The third and fourth letters, n and g were matched and replaced with q.
The third letter, n, was matched again and "replaced" with z

This is the product of gsub matching two different overlapping patterns.

is there a workaround for this ? LeadRDRK 437 — 7y
